Re: Soon to release bp group control plugin
Burt adsit created a plugin called bp-contents for group and member taxonomy, but it was never updated for bp 1.1 or above. I updated the group features to work in bp 1.1.2, but if I were you I would wait for the Buddypress team to add taxonomy stuff to the core (this will be better supported than my hacked bp-contents).
Any way, I hope to have some code for you guys to test out by the end of the week 
PS, if any one here has experience finding security vulnerabilities, I’d like to get some other sets of eyes to make sure my plugin is completely secure.
