Maybe a screen divided by 4 on on side and another one from the other side. Although 4 splitscreen on a 24 inch HDTV wouldn't be good, and the PS3 doesn't support 8 controllers.
I've always asked myself if the PS3 could use 7 bluetooth controllers and one USB controller, anyone knows?
I'm sorry, but what?
I think you need to include some more information in the OP because I have no idea what you're even talking about..
EDIT: Looked it up, does sound interesting, but the ability to split it up for 2 players is probably the TV's maximum capability. The PS3 cannot support 8 player splitscreen and the TV, I very much doubt, could ever support the display of 8 (make that 16 for 3D) full screen images at the same time, all refreshing at 30fps... that's 240fps just for 1 frame of each of the 8 images and 480fps if you wanted 3D...
So no, not even in theory could this thing allow for 8 player splitscreen.
