They are part of stock Windows 9X distribution.  You should be able to
find them in your WINDOWS\SYSTEM directory.

If you use START to run a DJGPP program, conagent is automatically
loaded into the VM that START creates.  I think redir32 is also
loaded.  The problem is how to communicate with them from another VM
that is not the system VM, and from a program that is not a native
Win32 program.  Someone (tm) needs to figure out how does this work
and then see whether it's possible to exploit that for our needs.  I'm
not holding my breath ;-).
