Using generated virtualenv in dynamic_reconfigure

[BoyanH]

Is it possible to use the generated virtual environment to generate dynamic_reconfigure parameters? As I understand, dynamic_reconfigure's .cfg files are just Python scripts, so I imagine it would be possible to execute them in any environment.

Background on my usecase (the Why?)
I am using XML files to describe a simulation environment. Each file can have multilpe scenarios or things that can happen in that environment. There is a library for parsing these XML files, which I would like to use to retrieve the set of possible (environment, scenario) tuples and allow each of them to be selected via dynamic_reconfigure.
