As a directv subscriber, I just got a flyer in the mail for the Hughes 2-way sat. system called DirecWAY. I'm in the same boat you are - no cable, no dsl. Were I not unemployed, I'd be jumping on that DirecWAY. You can also get single dish 2-way internet + video programming, which seems the hot ticket. It seems a little steep, $400-600 for the dish & equipment.
My issue with it is that the interface is USB, and only to M$ operating systems, which I rarely use, and certainly would not consider as an "always on" internet server. Once they release an ethernet box I'll be all over it. Well, assuming I'm solvent by then.
Thanks I'll sure check this out.
