I like where this version is going!
Meanwhile, between comments in different mailing lists, and comments on the
wiki in the old robot_mechanism_controllers, it'd be great if we could
aggregate this discussion. Really it seems like this is an extension to the
trajectory_msgs package, so maybe we can do an online review where people
can propose and comment on different options and subjects. I've started one
[1] with the initial proposal from the old wg review, and added Konrad's
proposal above (feel free to remove/edit that, Konrad). I think we can use
the robot control SIG to coordinate, and ping ros-users for high-level
notices. Then when we've at least gotten the scope down, we can initiate an
REP request. How does that sound?
