Just thought I'd give everyone a heads up about the status of OGA 2.0.  Drupal 7 and its modules have come a long way in the last several months, and it's at the point where I can set it up and play around with it without it barfing all over the place.  That being said, there's still one crucial module with an outstanding bug that's preventing me from getting a serious start on the OGA 2.0 codebase.  Once that's fixed, I'll start working on the alpha version.
