I shall try to give a 'professional' answer which should (hopefully) finish this thread off.
There are no 'live' ATC internet feeds in the UK because there is no legal requirement and it is not a CAA licensing requirement on the ATSP's to provide one.
Reading the PASSUR site there appears to be a need for ATSP's in the USA for the data which that company provides (although I'm a bit dubious about how the number of aircraft handled relates to when you need to re-surface the runway). In the UK (and Europe) things like En-Route fees are handled by a centralised computer system. 'Live' landing times at airports are taken from a feed off of NAS, hence you get a longer lead time for flights from the US than from France etc. So in the UK there is no business need as well as no legal nor licensing need. Therefore the ATSP's have no need to go to the trouble and expense of providing it.
