That's easy to do: let dhcp configure all the interface (maybe with fallbacks
if no dhcp server is available) and the call different scripts based on the ip 
address assigned too your ethernet card in netstart.local.

I'm using something quite similar on a Win32 machine, where it sets the 
proxy server, mail server, mail profile, customized link to the internet
browser (it copies a .lnk file to the task bar ;-) - of course the DHCP 
server runs NetBSD.
