Interesting ... so MS use P2P for Games and Dedicated Servers for Movies, Sony use P2P for Movies and Dedicated Servers for Games ...

Hmm, not sure this is a good move - I think MS have it the right way around.. (well dedicated gaming servers would be better). You certainly don't want somebody using your upload bandwidth when you're trying to game online - that's the one area where we all need extra capacity (talking ADSL here..)... And do people really leave their PS3 on when they've done for the session ?
Can't see why they can't provide dedicated servers - if people are paying for the movies, then factor in this into the cost.... ?
