From looking at dynamic_reconfigure it seems that 'sub-namespaces' (next best term that came to my mind) for parameters are not supported. My scenario involves a robot with quite a few parameters on a per joint basis. So essentially, there are PID gains and multiple more parameters per joint. It would be natural to have those sorted like 'joint0/p_gain','joint0/d_gain'; 'joint1/p_gain','joint1/d_gain' etc. Is it possible to achieve something like this with dynamic_reconfigure or another option?

Right now, there's no support in dynamic_reconfigure for sub-namespaces. However, this is a feature that's under development and should land in F-Turtle. We tried to get it in for electric, but pushed a bit to late and need to test things more to guarantee stability. If you're interested in trying things out, you might want to check out the review page for the feature: http://www.ros.org/wiki/dynamic_reconfigure/Reviews/7-1-11_groups.

To answer my own question: I just stumbled across a posting on the developers mailing list about extensions to dynamic_reconfigure that implement basically exactly what I have in mind: http://code.ros.org/lurker/message/20110707.150935.c81ffb51.en.html
