It's more a case of your client starting out with it's stand-alone
configuration.  Backing that up when it changes it to suit one network,
and restoring it upon disconnection (your client changing its
configuration based on what the DHCP server provides, not the remote
DHCP server actually changing things on the client).  And doing the same
sort of thing for the next network.

Automatically doing the sorts of things that you'd have done by hand.
