We are about to release our new BeagleBone motherboard that has the ability to add Arduino compatible boards. Because the Arduino is typically 5v, there is some adaption / wiring required but there are a lot of solder pads and headers that make this pretty easy.
We make a bunch of microcontroller boards based on the Microchip PIC 18F series called a HamStack and our boards are Arduino pin compatible. Well, as much as a PIC can be compatible with an Atmel chip We then put that footprint on our new BeagleBone motherboard along with a bunch of serial connectors (RS232, RS485, Xbee) and a socket for an audio CODEC. There is also a built in power supply so you can run your beagle off of any 7-20+ VDC power source. Very handy for solar / battery powered systems.
