with wp 3.0 utilizing post_types, I’m guessing a lot of people in the future are going to be asking about adding their pretty new data types into bp.

I would strongly suggest bp consider an easy UI for an admin to simply add in their post types and desired metafields for capture into the activity stream. The current setup is FAR from user friendly. I can see many cases where an admin will simply want to display their new info without having to build an input component.
