This seems reasonable. I guess there are synchronization issues,
though... it's no trouble to handle it in the (central) server, but I'm
wondering if there will be a problem synching the clients with each
other.

I'm actually not thinking of file-sharing, but of a game. So once the
server informs each client of the other's identity, there has to be
some protocol for determining who goes first. I could cheat and
let the server set it randomly, of course...

OK... so I'm thinking I could start with a port like 12345, and try it...
iff another process is using it, I'll get an error, and I can increment it
and try again until I get a success (or find that I've tried  an
unreasonable number of times).

Yes, that makes sense.

Thanks,
