We had Starband for about a year, till we got a T1. Results were mixed, service could be pretty good, or pretty dismal, or not work at all. Seems like we had to restart the server frequently as the program would crash. Download is much better than upload too. If you're just surfing the net, it's definitely better than dial-up, when it works........
Wildblue was just starting at that time, so I don't have any input outside of the things that are general to all internet satellite services. Namely, service will vary greatly, based on weather (they tell you it won't matter, but it does), time of day (heavy internet traffic in the am business hours, and at prime time) and that your upload time will be sllloooowwwww.
It'll also have substantial latency, so voice or video communication probably won't work. But like I said, it's usually better than dialup, and I'm sure they've improved it since we had it........
