Both items are not difficult to remedy.  If you're capable of C 
development at all, I can walk you through making a C116 version of 
C=Key.  I'd do PS/2 first, as I am working on USB here, and all but the 
PS/2 or USB codebase will be identical.

If you want to do PS/2 or USB to C116, you don't need the large C=Key 
form factor.  You need only 10 IO lines (8 for the cross point switch, 2 
for PS/2 or USB, and 2 for things like RESET and maybe UART out.  An 
arduino AVR (M328 or something like that) has plenty of IO.

I'm happy to help.
