I'm still missing the point here. What's the point of "tethering"?
OK it saves taking out the card and reading the data to the PC, but is that all?
I have another Arduino board on its way that plugs directly into the back of a 2 line LCD (It's a prototype and not generally available yet).
You'll find a board that does that on ebay. Roboduino perhaps. WHat's special about the one you have coming?
1. Shooting HDR macro images where you can bracket exposures.
2. Adjusting the exposure to compensate for the exposure change between magnifcations. I've seen this quite a bit when I'm stretching the DOF.
3. Verifying the images are acceptable on a large screen vs tiny Live View LCD.
4. Verifying first and last images are covering the desired DOF. I've had this problem more than once.
I don't know if the new board is really unique, but it is the same size as the LCD so should make for the smallest package. I expect the price to be about the same as a regular Arduino board.
