I have a client who used Hughes service for about three months in 2005. He lives in BFE Northern Indiana and his connection sucked kinds of ass that have not even been invented yet. Could've been an installation problem, but he'd lose his signal pretty regularly in poor weather (rain, mind you, not snow). For some reason he'd call and bitch at me about it (then again, he also once paid me to come out and install a USB hub even after I gave him detailed directions and faxed him a picture of the back of his computer...), but when I was hearing from him three times a week, I got kind of sick of it.
Speeds were faster than dialup for long-ish downloads (guessing 256k or maybe 384k, actual speed) but web pages didn't load any faster than over a decent modem connection.
Eventually I suggested a move to ISDN, which was available even in BFE. With a demand-dial connection I believe his bill for that service is around half of what the Sat service would be.
I've worked with a couple of the precursors of the current Hughes service as well. I don't know if they still enforce bandwidth limits, but at least with EchoStar there was a hard transfer/month limit, beyond which they would throttle you back to modem speeds. That kind of sucked for someone paying $100/month for service.
Anyway, you might check to see if ISDN (128k) is available, or iDSL (192 - 256k). Both are cheaper and more flexible options. These days, at least where I live, packet radio (Airbaud and CSInet in northwest Indiana) and 802.11-based ISPs do exist, and can provide service in places where cable is but a dream.
