Hi Wayne,
You might be able to join forces with someone on Rennlist that's already started something similar. He seems to have the knowledge and determination, maybe not on quite the same scale, but it's already started. I've got no affiliation, but it seems like it's got potential. I don't know what the implications of conflict of interest in remaining "allegiance free" to any particular company.

Seems like a great and much needed resource though, whoever develops it!
