Reading the archives, the general consensus seems to be that the only
practical way to do this is to make GSM data calls to the recipient,
and put your own compression and encryption on top of that. The
problems with it are that apparrently it has much higher latency, and
the bandwidth provided may not be enough to even make a call.
