I'm interested in this too... am looking for a way to have
constant connectivity to my car/bike/laptop when away from
home, for purposes of telecommuting and media streaming
(also planning like 'gene to convert my physical media
into bits- anyone know of a cheap hardware MPEG-2 stream
encoder?).
I've investigated the commercial low power (unlicensed)
spread spectrum hardware out there and it looks like
it might be possible to setup a small cell of connectivity
by placing a omni antenna on my apartment roof and a
second one on my car, but I doubt the radius could be
more than a mile...
