[Catalog-sig] Distinguishing PEP 345 distributions from old ones.

[Alexis Métaireau]

Heya folks,

Do you know if there are any ways to distinguish PEP 345 based 
distributions from other ones (distutils1 or setuptools) , when hitting 
PyPI?

That could be useful to have a specific record in what's returned by 
PyPI so we are able to decide what to do with them from there.

Any idea? If that's not something already available, any concerns about 
a possible implementation?
