With my knuckles getting stiffer, this is a really attractive idea - I just wish there were more obvious ways to get the stick on keys (cannot seem to find the links)
Edit: did not mean to sound so miserable. I think this is a great project and my plan before Xmas is to install it on a raspberry pi, buy or make the stick on keyboard and use the RPi as a pass through keyboard at work - so I am less dependant on each local hard disk
