While we're on the subject of supporting other processors, you know what would be really awesome would be XMEGA support. I'm not sure why they chose to go with the arm processor they used in the DUO, but that chip is huge and seems to require a whole lot of support circuity. I don't think I'd ever want to take that processor and stick a bare bones version in my own project. The xmega on the other hand comes in a small 44 pin version, looks easy to use, has a built in DAC for audio output... Aside from running a 3.3v potentially being a problem for controlling servos, for projects that need a little bit extra oomph, and 32mhz xmega seems like an excellent choice for an upgrade if you need twice the speed and/or audio output.
Well googling there seems to have been some working on such a port, but best I can tell progress seems to have stopped with Arduino version 18, so not likely easy to install for arduino IDE 1.0.x

There seems to also be a currrent kickstarter project that will have to deal with adding support to run on the currrent arduino IDE. However it doesn't appear he/she will reach their goal amount in the time left?
