In a nutshell -- DHCP won't work well in a Rivendell environment.  Early on in
the design process, I did experiment with using DNS to resolve hostnames.
Because of the non-deterministic nature of the DNS protocol (recursive
lookups, etc), it didn't play at all nice with realtime performance.  (When
the user hits PLAY, it needs to play *now*, not when some name server three
lookups away gets around to resolving a name.)  Hence, the static IP address
entries in the RD database.
