Korea loves FTTH too. I guess it's possible because the housing density is so high. (Say, a square mile might contain up to 20 apartment blocks, each with about 200-250 apartments on average... so that's maximum 5,000 households in one square mile!) Even more so on the very latest high risers, which go up to 60 floors these days.
Average ADSL speeds are 6-8Mbps, whilst VDSL is either 24Mbps symmetric or 48Mbps down / 8Mbps up. And most of new housing developments come installed with LAN sockets built in (100Mbps).
Truly the centre for ridiculous bandwidth. The problem is, what legitimate/legal uses are there for so much bandwidth? Most people end up using P2P with the newfound speed because there is little else that takes advantage of so much bandwidth.
