Older thread with advice/info about Hughes/DirecPC - skimming it quickly, it still looks to be up-to-date and accurate. The three main problems with two-way satellite are the latency, the usage caps, and the expense. It's horribly expensive to get set up and running - someone mentioned $35-$40 a month, but unless they've radically cut prices recently, DirecPC is around $70 a month, plus several hundred dollars up front for the equipment.
