[Galene] Re: About UDP multiplexing

Hi Dirk,

That's pretty much what we do.  When nothing is specified, we let the
kernel choose the port every time we need a UDP socket.

I'm not sure what's less confusing: using two mutually exclusive options,
or using a single option that's overloaded (currently, -udp-range does not
enable muxing, it merely restricts the range of ports used for un-muxed
sockets).

OTOH, we'll likely have requests for other functionality (binding to
a single interface, or binding to a single IP address comes to mind), so
perhaps overloading the option will prevent multiplying options in the
future.

I'm also wondering whether we shouldn't move this to data/config.json.
Right now, data/config.json is restricted to options that can be changed
at runtime without restrarting the server, but perhaps it might make sense
to relax this requirement and put everything except debugging options into
the config file.

Does anyone have opinions?
