A sniffer can be much more subtle than that. If you have at least one page view beforehand, like some kind of neutral title page, you can stick an image tag where the SRC is a call to a mod perl script, with all you want to know set as parameters <IMG SRC="/ninja-image.pl?has_plugin=1.3&...">. You can create the parameters using document.write in the page itself. That way, by the time you get to the second page, you have the info you needed.
The perl script ninja-image.pl simply gets the data and would store it in some kind of persistant way, and spit back some minimal headers and the binary data that would be some kind of image (like a clear pixel, even).
