The point I was (rather convolutedly, admitedly) trying to make was that the actual structure of the network means it doesn't matter *WHO* owns it, it's still going to go wrong for the same reasons - it's just the way that it's managed to be fixed when it *does* go wrong that would change...
... that said, that wouldnt be a bad thing
If 3meg is popular on Telewest and they can continue to provide it without any detriment to the network, they'll keep it, but only roll it out across everyone if the network can take it. otherwise it'll stay "Only available in some regions"
Those regions being ex-TW, of course...
