Can't do a graceful shutdown without a button.

I actually would be uncomfortable with something that didn't have
an activation sequence of some kind that didn't include something
that you normally don't do (plugging/unplugging is supposed to be
limited to installation and deinstallation, not activation and
deactivation).

Actually, you don't have to do the DNS thing, if you can do the
DNSUPDAT thing.  So:

o	Find the gateway
o	Find your IP
o	Find the name server from the root
o	Reverse lookup your IP to get the domain name
o	Use the DNS information based on your role to
	configure yourself

Role selection can be more difficult, but really, SLP can be used
to find a "manage me" server.

I'm a big fan of ZEROCONF.  8-).

Yeah.  This is what's called a "whole product".  8-).  It means more
than just the object itself...
