I--on Gentoo--use a concept to switch to a different runlevel when in 
different network environments. I use a program called quickswitch for that 
task. It copies around some configuration files (resolv.conf, conf.net, etc.) 
and then switches to a different runlevel. It works on Gentoo, because Gentoo 
has boot script dependencies. Therefore, if I change from network1 to 
network2, Gentoo will restart all services that depend on network.

Also, Gentoo has an unlimited number of runlevels. But I use three different 
ones, so you can use level 3, 4, 5 for different configurations if you like.

Ciao, Matthias
