I would be interested in such a keyboard. Sitting very off-center from the monitor and having to reach 10" or more for the mouse gets aggravating and adds unnecessary stress. A smaller keyboard means more freedom and better ergonomics for a lot of us.
Also, having a board like the Truly Ergonomic (split, angled and unstaggered) with your silent switches would be really exciting.
Congratulations on your new switch designs. I really look forward to trying them in some form, as I'm currently using a Dell AT101W with "Black Alps". It must have been tedious and frustrating getting your switches just the way you want.
