And BT's 21cn (21st Century Network) is touted as being entirely IP, and 
they're rolling it out to the whole of the UK in the next few years.

They've already started with a few small towns and AIUI they're working 
their way through exchanges as I type... My exchange is scheduled to be 
converted in Q1 2010.
