No there is no gamesharing and for good reason so that people don't get a game for free while the rest of us pay. It's the equivalent of piracy. They should remove gamesharing completely from the PS3.

 Well, does gamesharing mean that you can download it on multiple PS3's? Or does it just mean that you have to play it on that account? (or the accounts on that PS3?) cause I have problems with my PS3 in the past, so I did need to re-download it to different machines twice

This is the legitimate reason to us it but ppl just use it to get games for free.
