HAHA YES!!! A DIAGRAM!!!

Ok let me go back and actually read your post

Wow - I love the touchscreen idea. It's novel and cloning it would make is work with little overhead.... not sure how it would scale though. Also not sure what performance implications it would have. I can't imagine they would be that high... it is a 2d app right?

I love the optimus keyboard idea. I thought about using one when they come out - but they are rather large and I find that I only use my HHK to chat and nothing else except open menus, etc. I would love a OLED Xkeys but I rarely move my keys around so the utility would be only to switch between mage and warlock spells on the fly.

As for the foot pedals. I own both X-keys and Vetras. Both are QUITE heavy. Designed to be put on the floor and pressed with several pounds of weight. Not exactly ergonomic. What I would suggest is getting the Vetra box (or just the board if you are cheap - no case though) and making your own switches. That is what I plan on doing when I need the foot pedals to 10 box with (switch between groups). Any SPST switch (check mouser.com or digikey.com) should be able to activate the pedals and press and depress the key. Also consider a rocker switch which would be either / or. Not sure how that would work though with depressing keys.... but could be of some use.
