Like I said, people can locally patch their systems if they really
want to rip out fundamental things like multicast support.

Some folks might find it instructive to do a google code search
or similar on the multicast socket options this things dikes out
of the tree.

Even simple things like NTP will spew failures with this CONFIG_IGMP
thing turned off.  And that's just the tip of the iceberg.
