I had a random idea, add (yet another) post-commit hook that sends a request to this ‘application’ with the diff.

The application then stores the diff.

Gentoo Users and Developers can critique the diff, offering suggestions on how to improve the code as well as advice
in areas were the code is crap.

This may or may not be useful. Certainly non-developers may be miffed by the fact that many developers won’t ever read their
comments or may never incorporate suggestions into the tree.

However I think it would be an interesting application to write as well as a way for learning developers to get feedback from other
experienced ebuild developers and users.
