Add tag and category to status updates?

I love what you've done with BP Activity Plus - it's 80% of what we need for the perfect functionality for our project.

Is it possible to add categories to status updates? - not blog categories, but have status update categories - to be able to categorize updates, say, Red, Green or Blue category?

Further, it would be ultimate to be able to have tags associated with updates as well. This way all updates with a certain tag can be viewed on one page - the "status tag archive" page.

How much would it cost to have you super-mondo-pros add these functionalities?
