Not shure how the Sony PS3 and PSP connectivity works, but the remote play option wich allows for the PSP to display the PS3 games cannot be generated on the PSP.
The PSP has not the power to generate the PS3 gfx, even in low resolution, so the remote play option has to be some kind of streamming. I believe the PS3 renders the screen into the PSP resolution and streams in a flash movie or some other way. The PSP is only used as a screen and the buttons as input.

Although the N800 lacks the psp bottons and analogs, it would be nice if we could do remote play in it.

So?? Is this possible? Anyone willing to take a shot at this?
