The main reason I looked at it is I was starting to write a lot of helper methods in the DataObject subclasses which would create their own DataContext and do a search and return a result. Of course, these live in their own DataContext and I didn't want to have localObject() calls to set relationships/etc, so I thought putting them in a shared DataContext would simplify that sharing process. The easiest thing for me might be to turn off the "Use Shared Cache" in CM. This will be a low-volume application, but it is important to always check the DB for fresh data in case the configuration changes.
