I can't see this working. Ok, the PSX and PS2 games would be streamed, but, it would be extremly annoying to be playing, say, Gran turismo 4, then, in the middle of the race, it suddenly stops, because more data needs to be streamed in. You wait and wait, and eventually, go to the bog. When you get back, you discover you lost the race because the necesary data had been streamed.
