Joe Brockmeier, Unexpected features in Acrobat 7, LWN.net, March 30, 2005. Brockmeier gives more detail on the Remote Approach technology that lets authors or publishers insert JavaScripts into their PDF's to track when and where their documents are being read. For example, Brockmeier reports that the spyware doesn't work unless the reader is using Acrobat 7. (Thanks to Chuck Hamaker.)
(PS: When I first blogged this technology, the news was that Remote Approach was developing scripts that would let publishers remotely disable PDF's and make them unreadable. Apparently that nightmare technology, which would make PDF's unacceptable for self-archiving, is not yet available.)

The open access movement:
Putting peer-reviewed scientific and scholarly literature
on the internet. Making it available free of charge and
free of most copyright and licensing restrictions.
Removing the barriers to serious research.
I recommend the OA tracking project (OATP) as the best way to stay on top of new OA developments. You can read the OATP feed on a blog-like web page or subscribe to it by RSS, email, or Twitter. You can also help build the feed by tagging new developments you encounter.
