	Interesting. This might involve a redesign of daemon mode for
the network stuff.
	Also, it might make sense to have a separate UDP listener in
any case. For instance, if a Palm has a network name or an IPv4
broadcast address as its primary PC, that might mean "send a wakeup
packet to this broadcast address and ask for a sync server." Then you
could have one UDP listener per network, and have it redirect
everything to the central sync server. Obviously not a big deal for
Joe Average home user, but it might be cool in a large environment.
