This article from Yahoo/techweb describes a spying technique that uses
features of Macromedia Flash:

http://story.news.yahoo.com/news?tmp..._cmp/160400719

If the link doesn't work, the title of the article is "Company
Bypasses Cookie-Deleting Consumers."

Apparently, the company United Virtualities uses Flash "shared
objects" in place of cookies. The article links to a Macromedia web
page that explains how to control "shared objects." I thihk that I
will just remove Macromedia software instead.

I hope that the anti-spyware vendors will provide features to control
these "shared objects."
