Pipelining between two SEPARATE Powershell processes - powershell

Question

Let's say I have two PowerShell programs running: Producer.ps1 and Consumer.ps1.
Is there any way to establish a client-server relationship between the two .ps1 files I have?
Specifically, Producer.ps1 outputs a PSObject containing login info. Is there any way I can establish a listener and named pipe between the two objects to pass this PSObject from Producer.ps1 directly into Consumer.ps1?
(Note: the two files cannot be combined, because they each need to run as different Windows users. I know one possible solution for communicating is to write the PSObject to a text/xml file, then have the client read and erase the file, but I'd rather not do this since it exposes the credentials. I'm open to whatever suggestions you have)

I found this link that describes how to do what you're requesting:

I tested it and I was able to pass data between two separate Powershell sessions.
Server Side:
$pipe=new-object System.IO.Pipes.NamedPipeServerStream("\\.\pipe\Wulf");
'Created server side of "\\.\pipe\Wulf"'
$pipe.WaitForConnection();
$sr = new-object System.IO.StreamReader($pipe);
while (($cmd= $sr.ReadLine()) -ne 'exit')
{
$cmd
};
$sr.Dispose();
$pipe.Dispose();
Client Side:
$pipe = new-object System.IO.Pipes.NamedPipeClientStream("\\.\pipe\Wulf");
$pipe.Connect();
$sw = new-object System.IO.StreamWriter($pipe);
$sw.WriteLine("Go");
$sw.WriteLine("start abc 123");
$sw.WriteLine('exit');
$sw.Dispose();
$pipe.Dispose();
