The G.998.1 part of ADSL2+ still mandates ATM as the transport. Given 
how BT tend to roll things it out I would speculate that they are still 
using ATM after 21CN migration, although I have no data to confirm this 
either way.

PPPoA is not going away any time soon -- it's written into the ITU specs 
for G.DMT-lite after all -- and there is a huge installed user base for 
that technology.

Whatever happens with 21CN is still going to take time to filter down to 
the rest of the populace. Also, someone's going to have to pay for it 

Of course the whole ruckus over ATM in ADSL with people in the first 
place, was that it locked them into using vendor gear, effectively 
denying people control over their own IP endpoint address, and 
restricting the services they can use as a result.
