One of the problems with satellite is that they are parked in geosynchronous orbit 24000 miles up above the equator. This means that the roundtrip distance the signal has to travel is more than 48,000 miles. Since the speed of light is ~186,300 miles / sec this means it will take a full quarter of a second for your signal to get to the satellite and back to the ground station. Then another 1/4 second for the response to get back to you. So a MINIMUM of 1/2 second to ask for something and get a response, just in signal travel time. Yea, it works. And yea, if you are in a location where that is the only option then it is a damned fine option. Otherwise it is less than optimum. For example, Multi-player "live" games can get hairy when you see something and can't "kill it" for a full 1/4 second longer than the opposition. John W.

The only real problem we have had is that VPNs are impossible per tech support. Hunter figured out how to make it work, but it is still a terrible connection.

How much is the International LD? It may be cheaper to dial in through someone in the US, and just pay for their second phone line (which is about $10 a month)!
