How to Manage Linux laptops on and off the network?

[Boutet, Jeff]

I know this is more a sys admin thing. But it is somewhat relavent.

My company is currently in the process of replacing all the Linux
development desktops for laptops, as to increase our developers mobility.
Thus the laptop will have to perform in 3 modes no network, our network,
someone else's network (using DHCP). Other than custom scripts, run levels,
rysc, anyone have any idea's?
