it's actually becoming common here - at least three companies now offer a 100mbps connection, hooking into a 1gbps local backbone, hooked into a 60gbps national backbone. it's still pretty expensive, but the prices are dropping constantly. the main problem is actually getting it, given that it's very common for landowners to have an "arrangement" with a local provider - they limit competition by only allowing one company to hook up the apartment complex, and get nice kickbacks..
interestingly, i can pull 20mbps on my connection on a japanese server, but testmy.net's servers generaly show me at around 4*5 mbps, so there's no point in posting my results...
