P2P Solutions To Legal Game-Related Downloads?

[TASF]Overkill writes "As 'P2P' slowly becomes a synonym for 'illegal', the perfectly legitimate and still very useful capabilities of P2P emerge. Modifications, demos, trailers, and other game-related files are typically downloaded by a lot of users all at once, something that kills the client-server setup of most websites. Game Philez is using Gnutella, ED2k, and G2, to help users avoid the long lines at other download sites, and helping to ensure that P2P stays useful, even for the DMCA-fearing citizen." With legal game-related BitTorrent solutions like FileRush and GameTab also out there, is P2P a viable alternative to the subscription download services?
