We use this already (Score 1)

I find this topic interesting and all the discussion around it because this is the exactly the technology we use for our ISP here in Iowa. Check out their homepage for a look. The reason we do this is that here, in remote areas in the midwest telcos don't think we're worth enough for DSL, or even cable (even though we have digital cable from AT&T). Its not bad speed, standard rates are 128k/sec but you can purchase up to 1.5 m/sec. I get great signal all the time (which is the hardest part of the whole ordeal) and unless the main servers go down, I don't have any downtime. Hey, don't knock it till you try it...
