Well lets start of , the day the rumour of a PS non-Interactive was formed. I went and asked a rep that I had personally new (whos name I shall not disclose here) revealed in a conversation we had that the purpose of not having a server running for online featurettes, was that the PS3 itself was going to be the server (I know *HUH!?*), let me explain the PS3 will work like a decenterlized network 1gb of each 10gb embedded HDD will be used to support this feature. Also further on in the conversatiion he told me they were planning to embed a new feature similar to GAMESHARE on the PSP, where you select a friend where he then downloads a level of the purchased game, to play with you (he currently doesn't know what the player support is). The game is then discarded after the Station is restarted or the mission ends (saving the stats to your profile). The rest of the conversation was on other tidbits like the neew Vista and last nights HD football game...
Well I probably thought you would like to know this bit of info, since his not that intrested in games to go looking around here.:D
P.S Ofcource in the end this is only one Sony Dev to another Devs whos pretty much broke... :P
