I'll add this to my queue, but it's a very long queue, and my current crisis has passed.
All of *my* data collection plugins write out .roi information in .csv files. Alas, I didn't have any control over the data collection in this project. I now have it down to a couple of mouse-clicks and a cut-and-paste to turn the .roi files into clear-text polygons. That will have to do, for now.
