I would agree with double blind.  But a max of 1 talk per vendor might also go a long way.

On the call yesterday, Dan asked me to send out my thoughts on double-blind reviewing.  My e-mail quickly turned into a blog entry:

Something that I probably didn't highlight well enough in there is Kathryn McKinley's excellent piece on double-blind review:

There are certainly lots of ways to attack this problem, but I view double-blind as an essential piece -- but probably not sufficient on its own.
