kde libraries are shared. There's a bit overhead, yes, but not alot.  However,
If the program isn't used it's swapped out anyway. Afterall we are doing UNIX
here, no?

?! KHotKeys uses KGlobalAccel just like Kwin, i.e. it talks directly to the
X-Server. The window manager isn't special, every client can talk to the
X-Server. The concept is called "passive grabs", KGlobalAccel encapsulates this
in a class and provides global configurability via a kcontrol module. 

With KGlobalAccel, every client handles exactly *its own* global accelerators,
i.e. KWin is reponsible for desktop changes.

KHotKey's purpose is to launch applications on hot keys. Pretty useful program,
works with or without kde.

However: when it comes to user-time (key events) and speed, a few
contextswitches really don't count unless you plan to type with at least 3000
keys per second.
