Bearfoil,
How many dollars per minute can you afford? Can you obtain the necessary satellite orbital positions to make it work? What are the rules for sending the data? How much power are you willing to dedicate to the problem? How much hardware expense is justified? Can you get the frequency allocations for this service?
It sounds like a good idea. It isn't, today. It may be someday.
We've been over and over this "solution" here. So far it has come up as not feasible if it is provisioned for peak traffic times for a typical 15 degree horizon to 15 degree horizon satellite.
