1. I wasn't aware of anyone else working on this - I can find no trace of what Farhad has done, so I don't know whether he has already started/finished what I just did.  I've added him to this RR, though.

2. I had none.  I wasn't aware of that, no, although this RR is the obvious first step for the stuff in that document.  I just turned up on #plasma complaining about the fact that screen locking doesn't work in netbook mode in Plasma (due to the lack of krunner), and aseigo metioned that the consensus was that locking support should be in kwin.  I volunteered to do it.

I'm doing it like this because the KAction/KGlobalAccel interface is not rich enough to do this (probably wisely - this isn't something apps should generally be doing).  The shortcut deregistration happens in KWin rather than KRunner because I don't want to rely on the order in which KWin and KRunner are started (or even on KRunner being started at all).
