Ok. Can you list/describe of what base kit you give the kids? Maybe
put it on a page on wiki.laptop.org?

I'd like to buy an arduino kit set for a basic robot, with the same
motors and sensors as you're using. So we can test here in the office
:-)

I'll publish to dev.l.o and send you a pull request.

Yeah - we can patch it on a suitable rpm for F9 builds. Are you still
targetting F9-based builds?

Yes, but you always need some "root-privileged" preparation to get to
the /dev node.

So include nxt-python in the dextrose build, or install the
/etc/udev/rules.d file. I think it makes sense to simplify things and
depend on nxt-python.

nxt-python sets the /dev node to 'lego' group, so you'll need to add
the 'olpc' user to that group.

I plan to do all of the above for our F14 release :-)

Fedora is pushing for more robotics tools in the distro --

Exactly :-)
