Something I would like to see is a good way to connect to the GPIO pins on the Raspberry Pi externally for additional functions. I am trying to figure out a clean way to add an XBee to my OSPI. The best way I have thought of is having the Raspberry external to the enclosure. I have breadboarded a daughter board that stacks on the Raspberry, which is external. The connector is a stacking type so the OSPi could connect onto to it that way. Not as clean as I would like.
Also, have cut outs on the top enclosure so USB devices can plug in as well as hard connected Ethernet.
Thanks,
Chris
