One note on the CLA issue - Allison Randall spent some time discussing the CLA in person with Anatoly at the PyCon US 2011 sprints, so he may have signed it then.
As I understand it, the CLA itself gives the PSF the rights it needs to redistribute under a different licence, while the accompanying licence covers other aspects (like patent rights and assertions of provenance).
There are certainly simpler schemes in the world, but our current one isn't *that* complicated (although an explicit official explanation wouldn't hurt).
Cheers,
Nick.
