Using 2 Keyboards Possible (for triggers, quick keys)

Greetings,

I have, for some time now, been trying to find a way that I can hook up a SECOND keyboard which I would use exclusively for triggers (quicksilver) and quick keys shortcuts. Is this possible?

There are two issues to get around:

1) for the hardware to recognize a second keyboard
2) for the software to make a distinction between the first and second keyboard inputs.

Does anyone have a bright idea. I do some product design and find that the analog system (single button for a single action, dials instead of push button incrementing etc.) is a much more efficient way to work. I Have most of my current keyboard shortcut keys used up and REALLY want to be able to set up an additional keyboard.

Anyone have some bright ideas?
