NFS ID mapping

[David L Stevens]

	IP address is better than Ethernet address, though. "Manufacturer"
ties "universal IDs" to hardware that's widely distributed, where an
<IPaddr,uid> pair helps you find someone in the global community of ids.
Routing information is encoded in the uid *and* the IP addresses are already
assigned.
	In fact, translating "user at host" into a 6-byte <IPaddr,uid> is trivial.

	This probably shouldn't stay in bugs.4bsd; guilty as charged.
