Sadly this doesn't always work. We have a similar system here in Italy (Telecom Italia own pretty much the whole phone network, and it's forced to rent it to other ISP, at a low price because it's considered a monopoly). Fine, yes? No. The other ISP just rent less bandwidth than they'd really need, so they can't offer a decent service (during peak hour it's very easy to get less speed than what you'd get with a 56k). It doesn't help that we don't have a cable network too, so we're stuck with the phone one. This mean low theoretical max speed (20mb down and 1mb up, with adsl2+), and the signal get really bad as soon as you get a bit far from the central. Now, this is (very slowly) changing, the bigger ISP are starting to get their own infrastructure and some big cities are starting to get cabled in FTTC (no FTTH because "or copper network is good enough" [sic]). I've also the feeling that I won't see FTTC anytime soon, even if I live ~10km from Milan. There's also to say that there isn't really any interests for high-speed internet. Last I've heard, only 15% of the people reached by a 20/1 connection buy it (preferring the slower 10/1 or 7/480k, which cost respectively 1€/month and 5€/month less).
