Thanks, Michael. I've felt the need for some time (I want to replace a kludgy multi-RC-servo controller on a grandkid project), but not the confidence and energy to try to make something up myself. I'm sure I'm overreacting, but the emotional rush people seem to be getting over the size and cost of Raspberry Pi's obscures the fact that many non-x86 hardware platforms exist out there. Please don't make it sound like your solution fits only one. And "appalling RT performance" is a relative term.
