My mom used to be on Hughesnet, shared from a neighbor. It was horrible with the daily limits, as once the threshold is crossed, speed drops to near or below dialup speeds. This made it near impossible for her to download anything large. And if it was a security update day, multiple computers could easily ensure the limits was crossed. I think their plan capped at 300mb a day.

She has since switched to Wild Blue, and is much happier. Instead of a daily limit, it's a 30 day rolling window. So if a big file has to be downloaded, it can be done without crippling the connection. Overall the speeds also seem quite a bit better. It's been the first time we can reliably do a video conference call, though audio still is best over a phone due to the satellite lag.
