Facebook chat, GTalk with XMPP? - facebook

I'm still not quite sure what XMPP is. However I understand it is a protocol which drives many IM services such as FB and GTalk.
What I'm asking is, is it possible for FB accounts to chat to other XMPP accounts (e.g. GTalk) ? Like #hotmail.com emails can email #gmail.com (decentralized) rather than only hotmail.com to hotmail.com etc.
Thanks

Sadly not. At least currently. Facebook does not federate, meaning it does not make or accept connections to or from other XMPP servers.
Of historical note is the fact that Google did not originally federate gmail.com. They enabled this 6 months after they launched Google Talk. There's hope for Facebook yet. Maybe.

Facebook does not provide an XMPP server, just an XMPP API, so it's not possible to have all the operations available at a XMPP server.
As you can see from this link
Facebook Chat should be compatible with every XMPP client, but is not
a full XMPP server.

Sharing Jabber chat session between multiple clients

I'm using Jitsi on client side and ejabberd on server.
It seems that the chat sessions are specific to clients, i.e. if I'm logged in to the same account from 2 different clients, there will be 2 separate sessions, and one can't see what's happening in another.
Is it possible to share the sessions for the same account on all clients? Like Skype or GTalk.
If yes, is it a server configuration or client?
Thank you.
I think what you're looking for is XEP-0280 Message Carbons. Basically the server takes care of relaying the chat to all of your online resources so that you have the same chat session across all devices.
You even get chatstates from all of your other resources so you can infer whether or not you should show an unread IM notification to the user on your resource or not. You'll need client and server support for this, and it looks like ejabberd has implemented it via this module.

connect private XMPP account through gtalk

Recently started at a new small company that has the following infrastructure:
Private XMPP Openfire server that hosts #chat..com
Google Apps for email, chat, docs, etc. with account of #.com
The company uses the private/internal chat server heavily for communication. However that requires me to install and run a client on my machine like Adium/Psi and then chat history is stored locally etc.
Since getting the entire company to move away from their beloved internal chat server and use gtalk that comes built-in with google apps is not an option, the hope was to register the #chat..com account with gtalk and then handle all communication through gtalk similar to what folks have done with AIM, Facebook, and other transports. Benefit would be the following:
All chat history stored server side on gtalk side and serchable
Other people in the company do not need to change behavior
Android phone that is already sync'd with Google services will not be able to leverage the chats without the need to install another XMPP client.
No need to have a thick client installed on the desktop/laptop
I have researched the XMPP transports and tried to the registering but they do not seem to cover my situation. I have investigated two routes thus far with no luck:
Transport plugin for Openfire
Use public transport at http://jabberd.eu
Guidance and/or experience from someone who has accomplished this would be appreciated.
I've used Spectrum (v1 and v2) to connect Openfire to Gmail and Facebook. It shows up in the users' clients as a discoverable service. It requires that a remote roster plugin be added to Openfire and that Spectrum be run on the same box as Openfire.
In short, it acts similar to a web proxy. Your users don't have to change their account on your system but to Gtalk users, your users appear to be other Gtalk users. Any of your users who access Gtalk will be using their own Gtalk authentication so you don't need to maintain any extra authentication schemes.
Take a look at it at http://spectrum.im. The remote roster plugin for Openfire is attached to the bottom of the first message in http://community.igniterealtime.org/thread/46580 (it's filename is "gojara.jar").

Facebook Chat, XMPP, Setting presence?

When changing the presence in Browser (offline/online) in Facebook Chat, the chat system sends the XMPP message in form:
<presence to="-myidhere#chat.facebook.com/adfskjfskjdfh" from="-otheridhere#chat.facebook.com" type="unavailable">
When I send my own presence from non-browser side (xmpp client) to the browser side with exactly same syntax, it seem not to effect. What I am missing here ?
Thanks a lot,

It seems like you can't do that with the facebook xmpp implementation, as they write in the documentation:
Facebook Chat should be compatible with every XMPP client, but is not
a full XMPP server. It should be thought of as a proxy into the world
of Facebook Chat on www.facebook.com. As a result, it has several
behaviors that differ slightly from what you would expect from a
traditional XMPP service
There's an open bug on this matter: XMPP: can't change availability, and also this thread also talks about it: Xmpp chat invisible presence.
Also, don't expect the fb apis to have the same functionality as you get using the fb webpage.
They obviously don't open everything they have to the apis.

How to receive push notifications from my Gmail account?

I'd like to write an application which monitors a mailbox (ideally a Gmail mailbox). In brief, my question is how do I listen to incoming emails? I could always keep pulling emails but I am afraid that this doesn't scale very well.
How does iOS do it with Gmail? I think they are using Exchange protocol, but I am not sure. Does anybody have an idea on how to do it? Is there a solution which already does something similar? I just need a hook.
Thanks!
The most universal "API" for monitoring a Gmail or Google Apps inbox is the IMAP protocol. There's some information about this here:
Gmail IMAP OAuth for desktop clients
For Google Apps inboxes (not general consumer Gmail accounts), you can also use the Gmail Inbox Feed, which provides an AtomPub XML feed of unread messages in a Google Apps inbox:
http://code.google.com/apis/gmail/docs/inbox_feed.html
The "API" to GMail is IMAP.
In IMAP the IDLE feature is used to tell the server to notify the client when there are changes to the mailbox.
IDLE is defined in RFC 2177 IDLE is an optional IMAP feature so this may or may not work on other IMAP servers.
If you just want to talk to Gmail, they have a REST API you can use and it supports push notifications (e.g. webhooks):
https://developers.google.com/gmail/api/guides/push
But again this is a Gmail-specific API, which may fit you requirements or not. If you are fine just being specific to Gmail it is likely easier and better to work with from a web/mobile type environment than something like IMAP.

please suggest a good XMPP server with an automatic account registration

Maybe you could suggest a good XMPP server, such as icq.com , jabber or livejournal, that would accept automatic account registration from an xmpp client, not from their website.
Thanks! ;)
Many servers support XEP-77. You can find a list here:
