Further on the "open source ecosystem" chain

Speaking of the blog by the "Director of Ecosystem Development for the Eclipse Foundation", he posted an entry discussing an interesting study on the success of OSS projects, in which he made the following comment:

To me, success would be a healthy ecosystem with lots of commercial and non-commercial activity. This would be pretty difficult to measure, not only to find publicly available data, but because it's not clear how to measure the "health" of an ecosystem. There is hopefully an opportunity for research in this area moving forward. (emphasis added)

BINGO! I think I have an interested reader here...I DEFINITELY need to give him a shout out when I get close to an answer.
