This is easy w/o any special libraries, if it is indeed all you have
to do.

Some options:

- Clients open TCP socket to server as a "subscription", server dumps
  all the changes to all the connected TCP sockets. 

- Clients register their host, port addrs with server, server sends
  updates to all the subscribed clients in UDP packets.

- UDP broadcasts might work too, haven't tried it.

Or, you could use something like CORBA (omniORB) for more complicated
scenarios.

But beware: OSE, which that recipe relies on, seems to be licensed
under QPL.
