A few notes.
It is important to show files from hidden releases as well as
unhidden releases. I suspect the select statement above does that.
I parse long descriptions to get #egg= links. I also give some
special care to urls that point back to PyPI to avoid having
setuptools go back to the human interface.
It might be easiest to just trigger the existing ppix sw to poll
after a change. Thanks to your xmlrpc addition, polling is quite
cheap. Alternatively, we could install the existing software in a
way that polls more or less continuously. This would be quite
trivial. What you suggest is probably cleaner but requires some
expertise with the current software. :) I'd much rather generate
static files (as I'm doing now) than serve these dynamically.
