This would mean, I can "kill" other users multimedia applications by logging 
in. I don't think this is desirable.

It is theoretically possible (even today). For example today amarok has a DCOP 
interface. You should be able to authenticate yourself to the DCOP session on 
the "old" VT, and then issue DCOP calls. This should theoretically also be 
possible with  some kind of KDEMM.
I have never tried it, and don't know whether it is really this easy. And I 
won't answer questions or speculate how this is possible, becuase this 
discussion would rather lead to a lengthy IPC/Security discussion.
