That's an interesting idea.

Low, in the short term. A good first step would be to work out a
somewhat detailed proposal including:

- Descriptions of specific situations where this would solve a
  problem, with specific examples of how the proposed meachanism would
  be applied.

- A syntax proposal.  It has to address distinguishing file paths from
  urls from these new things. I suspect these should be expressed as
  URLs, e.g.:

     project://some.project/aconfig.cfg

I'll note that I suspect you can do this now using a buildout
extension that installs a new URL handler in urtllib2.
