Thanks to all for your input.   I have tentatively decided to skip all
the local discovery stuff and just rely on an internet server being
accessible.  A simple LAN-scope server may happen later.

I did look at the 'rendezvous' type libraries, and they would be
attractive for a LAN-only game, but trying to share peer listings
between the 'rendezvous' source and internet server source seemed to
reintroduce the complexity.
