At the moment I'm only concerned with point-to-point for two sites

> 2.  How much power?

I don't have a good description, per se.  I would like to be able to connect
over a couple kilometers of clear terrain and transmit no more than about
4KB/s.  There's a burst transmission that starts up when you connect that
contains a couple of kilobytes and then about a kilobyte every 30 seconds
or so.  There are also events that would be generated but that would be 
infrequent and they wouldn't be more than a kilobyte.  Overall I really don't
think I need much for bandwidth and could probably get away with directional
antennas on 802.11 but I'm worried about how fragile the link might be over
that distance with the potential of the antennas getting bumped or otherwise
out of "sync"

> 3.  Coould you use an rs-232 radio?

If I could do ppp over it then it would be great.  I have a lot of 
infrastructure that's set up to work fine using the IP layer.  If it's 
more of a minicom kind of thing then it could be used but I would 
have to work on a driver to abstract it from everything else
