Note: The PI's video architecture (like all these ARM class devices) is frame buffer,... Not X-server. I don't know if the MD code is written in a way that can take advantage of a frame buffer based video display tech,... You ought a ask l3me about that...
If you can get MD code compatible with the frame buffer drivers that these devices use,... that opens up a lot of interesting possibilities for inexpensive MDs, including Android ports, maybe even mobile/car MDs that can sever and reestablish their link to the LinuxMCE core, and operate independently when not connected to the core... Hmmmm,... Imagine the commercial possibilities for developers here...
