Looks good thanks

I have never used the Keyboard LaunchPad.  Where might I find a demo or tutorial for it?

I myself find mouse button shortcuts more useful than keyboard shortcuts.

Something like a macro recorder of events?

I use Keyboard LaunchPad, but I only use it to Pause/Play windows media player. I select a play list, and if the door bell or phone rings, a quick "ctrl+p" lets me pause things without the need try to find the player. I haven't done much else with it... yet.

I have the sudden urge to try to figure out what else it can do.

Anyways, you probally can't do this yet, but I would like to be able to pause/play Youtube. Like I said, the door bell and the phone are some of my worst hated enemies. To be able to "pause/play" websites like that would be a much welcome feature.

send commands to computers tied together via Multiplicity?  (i.e. CTRL-ALT-DEL)

Hm... Looking at that screenshot I got a bit of a headache.  I'd say start with icons for each program, then the user double-clicks the icon to bring up the possible commands for the program.  And if at all possible, (unless it's already included) have a check to make sure the keyhook you're using isn't already in use.
