It's being done elsewhere... (Score 5, Informative)

We have fiber to the building from our local provider in Sweden, Bredbandsbolaget (lit. broadband company). Right now they only run fiber to apartment buidlings due to cost issues, and the cost of installation depends on the number of households in the building that agree from the start to take the service. (It's not outrageous, but I don't remember what it was.)

It's very, very nice. We are supposed to get 10 Mbps symmetric, but typical speeds are a bit lower (something like 7-9). Granted that is somewhat confabulated by our use of WiFi at home as well. (Streaming full screen video to your laptop in bed... so what are YOU watching, eh?) Bandwidth-intensive applications were encouraged, last time I checked. Some TV stations are available as are movie downloads (real VoD!) and telephony.

Cost is similar to DSL or cable here and is around SEK 400/mo or about USD 55. (Current exchange rates make that look higher than it feels here.)

There is a similar service in Italy from Fastweb and in Iceland (I think by Reykjavik Energy).
