nope but a easy rule of thumb is almost all ex-nynex/videotron/Cable & Wireless areas can't do it

What is involved in providing CLI and what are the main technical obstacles ( part from the vast expense) to doing that?

1) see above
2) not cost effective till soft switches come into play (VM equivalent of BT's 21CN)
3) complete replacement of all switches and line cards. Billing system is not an issue now as all areas are on system designed to bill for Caller Display.
Biggest reason why some areas can't do it is the equipment was designed before Caller Display was thought of for landlines and was not designed to be software upgradeable.
For a feature that Virgin charges £1.75 per month for I am sure it would cost them more than that to upgrade a single line, let alone whole cities
