(("A Blueprint to Stop Browser Attacks
A software layer protects against cross-site scripting attacks."))
was summarized (and linked to) here:

I think this [topic] may be sorta "Hackfest" related. 
disclosure:  I could be wrong, since my knowledge of 
  "Hackfest" related stuff is limited... YMMV
(note: to users of the PLUG-Discuss archives:  due to a 
 bug which I think still exists, the "#412080" ["fragment"] 
 portion of the 2nd URL above might not be "linkified" 
 correctly -- or, at all -- 
 so you might have to click on the title -- which is 
 "A Blueprint to Stop Browser Attacks" -- once 
 you get to that "[...]/may-15-2009.html" web page.)
