I've thought about this as well. It would cost more, but I could get a really small house at the edge of a city, set up a Ubiquity tower, maybe licensed, and have my own radio link. I managed these links in the military and bad weather aside, they were decent. I too would be ok with 40/15 myself, but family members need more. I might catch some flak for putting up a small tower. I would like to avoid the commercial wireless solutions so that I could have more control over jitter/latency.
