And that chaley would really be perfect.

With respect to python scripts.
They could almost serve as a kind of small apps which the community can add to Calibre.
When apps become popular, simply add them as feature to calibre.

But a bit of basic plumbing and community attention is required, like
- some small examples
- a menu ability in Calibre - which adds for instance the ability to run it against a selection of books (not sure how to do that from the command line)
- a place to post them
- a means to add review comments, etc
- moderation and management

While the first and second items are relatively easy to achieve, the rest requires far more attention and work to pull it off.

Not sure how this worked for the news sources, probably that is the best example.
