Similar to the recent work on the Raspberry Pi - QCN & BOINC now work on the tiny Dreamplug ARM computer. The Phidgets 1056 and ONavi USB sensors work on them (I'm looking into the JoyWarrior problem). The Dreamplug seems to run much better than the Raspberry Pi - probably due to a better/faster USB implementation (although it costs US $159 versus US $ 35 for the Rasp Pi).

Here are the instructions:
