"Open Source" Drive Systems

I've been doing a little thinking lately (always a scary thing), and my brain stumbled upon this idea. What if students from FIRST teams across the globe banded together to create a set of "Open Source" drive train designs? I use open source loosely, more of the idea that we'd post CAD files somewhere, and make them available to anyone who wants them. I think it would be an interesting idea to try and get rolling, and here's why.

Rookie teams would see the following benefits:
1. Advanced drive systems pre-designed, available to modify however they see fit, with those who know how they work willing to give advice/help.
2. A starting point to look at: Sometimes you need to see a few ideas in order to get yours off the ground.
3. For the more advanced teams, it would give a place/area to pool ideas and make "teh most Ultimate drive system EVAR".

I was thinking there could be some sort of "admission price," or basically the posting/uploading of some sort of design or improvement.

So I'm looking for some thoughts. Would people think this a good idea? Or is this another of those ideas that I usually put out of my head?
