We started out yesterday morning and we split into two teams:
The PAS Integration Team is tasked with integrating PAS into Plone as an alternative to GRUF. So far they've produced a product and test cases for everywhere that PAS breaks in Plone and some documentation on the various plugins and stages of PAS's toolchain. Their Friday goal is to have a distributable product that people can start using and testing to drop PAS into Plone.
The CMFMember Team is tasked with better Plone/CMFMember integration and a major refactoring of the code and tests. They have a release candidate that went out yesterday and will be spending the rest of the week developing new features, tests, and documentation.
