Would be nice.
Internet CAN work in geo-synchronous orbit. That is how I access the
internet. 650 - 900 msec latency (based on ping data), but doesn't
really matter. VOIP might be entertaining, but it can be handled.
Anybody who's used a satellite phone knows about and the adjustment
isn't that hard.
