how politely can one argue with vendors?

Immediate ALA past-president (and my former professor, longtime mentor, and all-around earthshaker) Dr. Loriene Roy and I attempt to answer this question in the new ALA Annual 2008 Conference podcast edition of the Library 2.0 Gang. Argue about what, you might ask? Privacy, library innovation, the deadness of the exhibits floor, how involved vendors should be in conference programming, and (if you make it through minute 50) olfactory marketing.
