Hi Dave,
To answer your question directly I have seen a proof of concept with roscpp
running on a bare metal arm chip. I don't know exactly what went into
making that work.
Morgan,
Thanks for taking the initiative to setup the SIG. I've created a wiki
page for the SIG at
http://www.ros.org/wiki/SIG/Embedded
