this is kinda a weird/bad idea. first i bet the latency would be horrible (but i guess for loading levels thats a moot point). second, it would only be fast asumming u have good hdd in a pc with good i/o with good networking (like a gigabit switch wit cat 6 cable). third i can;t see any game company saying "u get this game that u have to swap discs, but if u have nas and a fast ethernet u can jerry-rig this gehtoo hdd so u don't have to swap", this would be to complicated and not "clean" for the people using it. while it could work in therory (and may very well be a good idea, for instance since i have a raptor and a gigabit switch in my room i could have the xbox think its a dvd drive and stream a "back-up", which may be pretty cool), it wil never happen as devs will never do it and it will only benifit the few (maybe with mod-chips tho).
