Uhhh, excuse me, but have you ever looked into purchasing a professionally 
constructed radio modem? First off, most require an FCC licence to operate, 
and second, they are outrageously priced! I have been investigating just 
such a purchase for the facility I work at, and prices in the neighborhood 
of $2000 per unit are what I've seen. (granted 9600 baud, but...)

$200 is not unreasonable if the error rate for this *thing* is low.
