A very long way, you're talking around the range where BT struggle to deliver 1Mbit, around 5KM of line length or 3.5 - 4KM as the crow flies. I'd guesstimate (well based on some fact!) that 90-95% of the lines in the UK would be capable of 400k+ upstream on ADSL2+

You could subscribe to a package that offers 24mbit downloads and only get the equivalent of dial-up speeds and the ISP could rightly say that you are getting what is advertised. As ISP's provide faster and faster speeds then the likelihood of getting anywhere near the stated maximum is reduced considerably.

Find me an ISP Ian that doesn't advertise 'up to'. It's all part of a contended service and the only services that aren't advertising a quoted maximum rather than a guaranteed speed are leased lines.
In my opinion this is a very unfair comparison as with the Be and UKOnline services, as with all DSL services, the
maximum speed is limited by line quality and length which isn't an issue with active cable networks.
The 10Mbit that ntl and Telewest advertise is also a maximum 'up to' speed which is governed purely by bandwidth utilisation rather than by line length.
However the advantage that Be and UKO have is that they can purchase a 1Gbit connection from the exchange to their backbone, multiple if required, whereas ntl / Telewest are only able to offer 38Mbps shared to each area.
Apples and oranges it is indeed, but then so is comparing distance limited bandwidth and contention limited. Unless you can change the laws of physics of course.
I'm not being a fanboy or a hater I'm just setting out the facts as they are here. Contention bandwidth wise will be a plague to cable networks for the foreseeable future and distance limitation to DSL based broadband services and that's the nature of the beasts.
