it looks like there are some new, competing standards here... a friend of mine tried to tell me that VDSL was the future yesterday.
but I had to argue ;-) VDSL is extremely short range, and i dont think it can be seriously considered, except maybe in new subdivions.
ADSL2 however extends on RADSL's range. it looks pretty cool.
there are some whitepapers here:

what do you guys think is a better standard?
