I responded on the other thread, but to repeat myself, I think
networking stacks or "exotic" but useful peripheral support (CAN bus
came to mind) could be good BBB projects. And to do a BBB project
requires to have the BBB and able to run RTEMS on it. So we need that
proof in addition to the normal sparc/sis one.
