Update on this plan... I am going to delay merging the branch over to the trunk for awhile, perhaps several weeks, for several reasons:
1. the trunk is somewhat unstable at the moment. Things are going in and being backed out, errors in recent commits being found and corrected, etc. at a pace I simply cannot track during a merge 2. I am still waiting for Galen's commit of the CNL code 3. we are about to hit a long weekend, and I need to get moving again on development I had no major conflicts when sync'ing the branch with the trunk, so I don't think the eventual merge will be a problem. For now, though, perhaps it is better to let the trunk settle down a little before introducing another major perturbation. We can revisit this during Tues telecon and see where we go from here.
