Maybe they should use protected torrents so that the downloading would be easier on their servers.... BitTorrent is very efficient.... Since it would use the mostly unused MSDN subscriber's unused upload rate, then the distribution of Vista could be more easily done, similar to Linux OSes... And when everyone has Vista (after release) they could use their own P2P system on the Vista OS or use BitTorrent.... I think it is a good idea... *Prepares for flames*
