You should check out the protocals used in packet ham radio. There is a plethora
of software and hardware. They use a modem box called a TNC which seems to
have the low level stuff in firmware. I.e. simple serial port on one side and
modulation out the other. They have dealt with the problem of
not everyone seeing everyone else. Check with rec.ham-radio.packet. I'm sure
that they have a FAQ which explains it all.

I have watched a single bulleten board connect to multiple remote sites through
one TNC on one frequency so it should be possible. ham radio tends to have the same
cost considerations as we do.
