I'm with Emmanuel here.

All of this is addressable through an Transactions utiltiy class.

The next step is to identify what features to tackle first by sketching out a roadmap (alpha1, alpha2, etc with bullets next to them). I'll take the first stab at it.

Developers are mostly likely going to need this module to write an app, primarily if they are trying to avoid using EJBs. I still believe that we should advocate EJB 3.1, though, despite working on this module. We could consider it a half-way house for people who have been burned by EJB in the past :)
