That's quite cool, but I still see a couple of downsides with this.

  - It only works through buildout. Ideally it would be supported at the 
setuptools level, imho.

  - I worry that the management of lots .cfg files could be cumbersome. 
For Plone, we could probably generate one from the dist_plone package, 
which otherwise lists "known working sets" for installers and 
plone.recipe.plone.

  - This doesn't really solve the dependency problem. I can't say, "Give 
me Plone 3.0.1 or newer" in a third party package. That could probably 
done by having a separate "Plone" meta-egg which uses >= type dependency 
specifications, though.

All in all, it looks like a workable solution, though. I'd like to try 
it out in practice, certainly.
