IMHO I believe the guy I spoke to at AOL who said that they didn't have a plan to introduce a cap, I did see the quote you have highlighted, however, the same COS are used for both ADSL and cable and as they have never introduced any sort of limitations on any of their services in the UK I don't think they will start now.
And to be honest even if they did introduce a 1 gig a day cap it would still be worth the extra £2 for decent customer service, E-mail that works, newsgroup servers that you can access and the knowledge that Ntl are getting a smaller proportion of my money each month.
