I had a search round and didn't see this previously requested - sorry if it's a repeat.
My idea is such that you have a special video file on the PS3 end which is actually a live (or as close to as possible) view of either a virtual second screen from the PC or a clone of a selected screen in a multiple monitor setup. So basically I can use the PS3 and TV as an extra screen or just stream stuff from the PC to screen as in like a presentation for example.
Not sure how possible it would be with buffers and all that but thought I'd get the idea out there.
