Just thinking out aloud.... What about a web-cam (maybe a wireless one? Never tried to use them...) right under the mic, so that it takes a picture of the badge and shows it on the screen? Everyone (right?) in a meeting has a badge wit his/her/its :) name and affiliation, so privacy concerns are just comparable to those of wearing a badge.
Of course, this is not applicable to jabber participants, in that case you need a different solution.
