We are going to implement this now (using the categories package linked to the acs_object = user_id). Any objections? Furthermore, is this considered useful, as we will have to change at least acs-subsite to enable this? If yes, I'd submit it on oacs-5-1 once it is finished.
I assume that Jeff already has something like this working as part of the COP code, though I'm not sure if you added the KM tools bar from dotknow.org with users as well.
