Oh yeah.
Its all go with business ADSL2+, bring it to the consumer products.
Too many things can go wrong with it in the hands of end users - too many things a service provider could be blamed for, and lets face it most users have no patience for diagnostics. It's not a service that you can connect a modem up to and have any guarantee it'll work first time out of the box. Without quantifiable config and site setups, and decent 1st line diagnostics it's just too complex and expensive to support. Sadly, I think it's all down to money
