OK, so I see the rosserial_embeddedlinux package supports TCP, I didn't see that before.   But it does say "imbedded Linux", which is still considerably different from an MMU-less uCtlr.  So, is rosserial_embeddedlinux more light weight than its name would imply?

Is it possible to run roscpp on the bare metal, or does roscpp depend on a lot of Linux system services?  Of course, rosserial would be an option, but if you have an ethernet controller on chip, that seems limiting.  Or is there another light-weight ROS comms on TCP that I don't know about?
