I've been thinking a lot lately about a completely pimped out keyboard interface...
It starts with hardware (Type Matrix, Kinesis) and hardware accessories (petals, extenders). It continues with a keyboard layout you're happy with (Workman seems to be the most hardcore), either built into the keyboard hardware or selected via the OS. The keyboard layout in the OS can be modified as well. Then come deeper software hacks like PCKeyboardHack and KeyRemap. Then, softer stuff like keyboard shortcuts go in your favorite launcher/macro/shortcut app.
