It would be pretty cool if someone could modify this so that it can load a game off of a network share. Then you could store the games on your computer if you wanted to. Then you could access all of the games you own over the network.
I'm pretty sure the max speed of USB 2.0 is 480 MBPS. Since the PS3 has a gigabit network card, you could then get 1000 MBPS on a netowrk share and double your game loading times.
For me, I own about 30 games that I bought but I hate having to change the dam disk all the time. Because it is such a pain, i pretty much just play one game that is on a BL disk and I play the DL games from PSN.
Having to change the disc each time we want to play a different game is kinda like watching TV without a remote. What happens when you don't have a remote for the TV? You do not change the channel nearly as much and you don't flip around during the commericials.
That is one thing that is good about computer games that you can install and Onlive.
At least when I'm on my computer i'm only about 2 ft from the disk drive to change the game. When using the PS3 i'm on the couch about 16 feet away.
