Congrats!

A few questions that you may want to add in a FAQ.

  - NEO replaces FileStorage? Maybe typo?
  - What is the gain of using NEO over relstorage + mysql replication?
  - Why not include ZODB 3.10/Python 2.6 as a goal of the project?
    - I understand *today* the technologies use python 2.4 but
      ZODB 3.10/Plone 4/Zope 2.12 use python 2.6
  - NEO is a different protocol than ZEO?
  - What is the Blob story with NEO?
  - Any issues with 32bit vs 64bit
  - Backup/restore strategy of NEO

Other notes:
  - Maybe explain the goal of the project clearer:
    """
    NEO provides distributed, redundant and transactional storage designed
    for petabytes of persistent (python?) objects.
    """
  - A buildout for NEO would lower bar for evaluation
  - How do you plan on storing petabytes in a single MySQL server?  since
    that is the data structure backend for NEO?

Looking forward to reading the petrinet article - please send update when
it comes out.

cheers
