Well, when I got back from Drupalcon, we decided that getting 1.0 out the door with products that grant roles and file downloads was the best thing to do. That means my QuickBooks plans have been bumped a little unless someone wishes to sponsor the development. I'll be happy to draw up a roadmap as soon as I can, and I really do plan to work on this as soon as possible. I imagine it will be something like a filler project while I'm bugfixing the beta releases.
