That's not possible (currently) but GnomeMeeting should bind to all
addresses when starting, IPv6 and IPv4 addresses.

That is a bit different, but yes, GnomeMeeting is using PWLib for
everything that could give portability problems between different
systems (threads, sockets, timers, ...). That is why, as soon as the
french guy added IPv6 into PWLib, we had a more or less working
GnomeMeeting as GnomeMeeting relies on IPv6.

No, but the right fix would be to determine with GnomeMeeting binds only
to all IPv4 addresses and not the IPv6 addresses too.
