I was involved in that discussion.

Quick summary of the thread:

The general opinion was that this is effectively an Acrobat-only feature. In fact, it seems that one needs Acrobat 6 or 7 Pro to enable commenting in this way and that (at least on Mac) the "commmenting author" needs Reader 7 to be able to participate. That said, it was suggested that (though ill-advisable) the Acrobat security model could probably be readily breached in this respect by third party tools. I wonder if either (or both) of these:

allow it ? Setting comments is not AFAICS mentioned in the blurb, but similar tricks are. OTOH an academic license for 7 Pro is not *that* much more expensive.
