Not to my knowledge.  You see, XPC is a DOS TSR that listens on the Telnet 
server port (TCP:23).  While the TCP/IP kernel is reentrant, and offers a 
virtual machine interface that allows multiple DOS applications to share the 
stack, it can't handle two applications asking for the same TCP port number.

What the second XPC should have said is "port in use", or some such.

I'm not sure that Windows will provide the multitasking muscle you're 
looking for, but what we'll need to do next time is run a sort of 
Windows-based INETd thing that will spawn a new %COMSPEC% and an instance of 
XPC whenever one Telnets to your machine...  I believe B&W's Telnetd works 
this way.  We spent more time with the X-Client aspect, and didn't have time 
for the INETd approach.
