Frequency hopping in the 900MHz range.

I believe you can go modem-modem even through the repeater network.  As
long as the modem is set to auto-answer and you know the number, you can
call each other.  

You have to use starmode if you want to handle multiple connections, but
for single connections modem-modem is fine.  Metricom also sells
(sold?) gateway units that you could use to drop onto the POTS network.
