The pre-transfer email was 100% spot on, exactly the kind of thing I would write to help someone reconfig their equipment, good mix of noddy instructions and full tech details if required - always a good sign.

The transfer across was something that reminded me that BT Wholesale will have a big part to play in this little saga, as my VCI etc all stayed the same, just my username and password changed really. DHCP then gave me a Zen IP, so the connection up to the Radius server must be the same whoever you are with (assuming you aren't unbundled).

I believe this is how some people were suggesting that BT could handle the opt-in (by using different radius profiles) but would obviously encounter some obstacles as BT Wholesale have to treat BT Retail as a customer just like everyone else (Zen for example).

However, having worked on BT's spiders-nest of a network I can say that they all run equipment on the same infrastructure at some point, so splitting them apart is more of a business level excercise than a network level one.
