You may want to look more closely at the special Desqview routines which
permit tasks to communicate with one another.  Shared memory is a
reasonably common way for different tasks running under a multitasking
scheduler such as Desqview to share information, but you would have to
ask the operating system for a block of shared memory -- the same
variables do not by default and *SHOULD* not share the same memory.

Another solution, which might work better than simply sharing a big
block of memory (for one thing, shared memory may cause problems where
two processes interrupt each others updating of the area and as a result
leaves garbage in memory; for another, I'm not sure that it would be
easy to force Turbo Pascal's heap manager to allocate from this specific
block of memory) might be to write a completely separate application
whose only purpose is to keep track of the users who are currently in
teleconference which would tell the actual programs what they wanted to
know when they ask it.
