- 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.
