The mosquitonet project has done exactly that, on Linux, on top of
David Hinds' PCMCIA patches, for more years than I can remember.
(the mobile routing is a bit more iffy.)
Isnt about time we caught up?

I'd agree, except Linux seems to manage fine, and they do throw the
state away. (Maybe its becuase they bind the device name, in the
userlevel daemon, via the tuple space and/or MAC address?)
