Well, as I said, I haven't really dug in too far just yet. I'm still setting up the interceptor pipeline and making sure that all works before I try adding my own to the mix.

Ah well..You don't even need to do that. The main interface has a ton of methods to define, but it also comes with a "Default" implementation, letting you choose which one to handle.. I'm 90% sure there is a specific method / info in the parms passed in that you won't even need to track which objects were modified outside of the interceptor itself.
