[ros-users] Capability of ARM dev board for ROS host

[Kent Williams]

Thanks for the thoughts Arjun,

At the moment I have the headless ubuntu 11.10 on the beagleboard so no X
window. I'll just end up testing how many substantial nodes I can get
running nicely, but ultimately it's looking like these are just not suited
to be the main workhorse just yet.
