Let the hive mind of Engadget get that for you.
"As someone who doesn't reside in the USA, I was wondering what would be the best way to get internet for my computer in the US for a couple of weeks? If it were Europe I know I'd look for some prepaid data. Is there anything similar offered by American carriers? A MiFi or a data SIM that I can tether from would work, but I'm trying to maintain a tight budget. Help!"
I think this is an awesome system if you use it in the right place. This system would be used in a place that could possibly have up to four people watching tv at once all viewing their own stations. You connect your Xbox 360s or Media Center extenders up to it and everybody is happy in their own room watching whatever they want being able to pause and rewind and all that other good stuff. It could be used for a very large family, a small business or for some guy who has more money than he knows what to do with and just wants to brag to everyone that he can record four premium digital channels at once.
