We've been done the FTTH road countless times, especially with Chrome on RB... the cost remains at approx. $2000 per home to pull the fiber from the end of the street.... the cost to use existing copper lines to get HDTV into the home, for those close enough to the central office to get ADSL today... a fraction of that cost.
Ideally, I would love to see fiber to all homes, including mine... but it's not going to happen in the next few years (i.e. 1-5) for sure.... the economics simply don't support the model at this time. By the time it does, NVEI's technology (whether NVI still owns it or not is not my concern) will be as common as ADLS chipsets are today, and then some. IMO.
