Requirements look like a good action plan for those of us developing add-ons: * Snitz import ? * Multi-level category hierarchy (several hacks of this, nothing yet in add-ons) * Multi-group memberships (Jazzman's multi roles) * Hidden, locked, etc. permissions (in the core) * Scoped search--turning off certan categories from search results (Does this work with block category? Possible to set blocks temporarily for a search?) * Syndication (RSS2 and Atom feed add-ons) * Mailing list ? * LDAP (Hack, otherwise as easy as wordpress & People integration?)
I think anyone who wants a multilevel hierarchical category structure is going to be disappointed with Vanilla in general; it's antithetical to the basic ideas of Vanilla.
The Neuros OSD is pretty cool, though; the beta sold out at Thinkgeek in like a day.
