A cursory look at the document doesn't seem to show any prices above
622Mbps, but for that you're looking at about £160,000 a year or
£21/Mbps/month.
2GB per day, equates to 190Kbps (assuming a perfectly even distribution
pattern, which of course would never happen), which would be £3.98 a
month per user. In reality I imagine that you could see usage peaking at
about 3 times the average, or considerably greater if large flash crowd
events occur.
I would say that in the UK market today, those sorts of figures are
enough to destroy current margins, but certainly not high enough that
the costs couldn't be passed onto the end user as part of an "Internet
TV" package.

Both Bulldog (C&W) and Easynet sell wholesale LLU via an L2TP handoff.
It's been a while since I was in that game so any prices I have will be
out of date by now, but IIRC both had the option to pay them per line
_or_ for a central pipe style model. The per line prices were just about
low enough to remain competitve, with the central pipe being cheaper for
volume (but of course, only because you'd currently need to buy far less
bandwidth than the total of all the lines in use; most ASDL users
consume a surprisingly small amount of bandwidth and they aggregate very
well).
