dialup is useless pretty much and is hopefully dying out in favour of better connections
wireless networks are being set up, the one by google in mountain view for instance is a pilot project and im sure it will spread to other cities.
the main problem is, when the providers all have to use the same backbone - on which there is this packet discrimination, how can anyone offer a true net-neutral service when its out of their hands.
the only way to do it would be to build a backbone of their own - something that is hideously expensive.
Chances are the ISPs wont bother, and all will simply apply the packet filtering - leaving consumers with no choice at all
