	It isn't a protocol change to increase the max rwho packet size. It's
an implementation change. We've been running with large rwho packets for years
(our Sequents support a couple hundred users without even blinking).
	You need to increase the size in "rwho.h" and increase the max udp
packet size (udp_sendspace and udp_recvspace) in sys/netinet/udp_usrreq.c.
And FINALLY, you need to ifdef out the code that refuses to fragment broadcast
packets in sys/netinet/ip_output.c.
	All of the changes are trivial. I can provide context diffs if you
ask me.
