Arghh, customs!
I haven't tried reprogramming mine, since I haven't found the need. But I suspect the more turn-key you could make it, the better.
The only suggestion I can think of at this point is to change the DB-9 connector to a right-angle connector. That would require having it hang off one side of the board, or making the board wider than the Discovery Board so the DB-9 could be placed on the same edge as the ADB and RJ-11 connectors. As it is now, when all five cables are plugged in, the result is a little unwieldy because cables are sticking off in several different directions. It's not really a big deal, especially if the whole thing is hidden behind your Mac, but it would make it a little more streamlined.
