This is such a cool idea, and the nerd in me loves the alternate input idea.

My problem with this, and it's such a niggly problem that's it may not even be worth mentioning, is that this will only work when you've got the footpedal around and I'd be frustrated when I sat down at a computer and didn't have it.

Like the author's note about muscle memory and wanting to hit the ESC key. I'd be frustrating to get the pedal into muscle memory and then forget it.

Sure you can learn a new system, but it's nice to know that vim is vim, regardless of the device you're connected via. Same is true for Emacs. Boy, an ALT key at my foot would spoil me rotten.
