Add-on Collection of recent activity for a specific user group?

[intradox]

I'm wondering if anyone would be interested in making an addon where it just shows the recent activity feed of an entire user group? AdminCP would let me select/input usergroup id # and possibly select the content to show (All or select specific ones: posts, threads, profile posts, other news feed items?)

For my case, I have a "developers" usergroup which members would like to checkout from time to time to see their recent activity.
