Problem is, how would discrete power on/off be implemented? The bluetooth remote doesn't have it, so it can't just be added.

If the PS3 had a *consistant* macro that could be performed for power off something could be written, but the menu steps change depending on context.

I'm not at all familiar with how the remote's bluetooth works, but even if the remote knows whether the PS3 is on or off right now Ben is tapping into what's essentially the keyboard side of it.
