It's unclear to me how this would be different than standard panopticlick
with >50% of the users using TBB.  But those not using TBB with had browser
statistics like the rest of the web (for example, all of the tor2web

> Hi Tor Community!
> My name is Pierre and I'm a second year PhD student from France working
> on browser fingerprinting. I'm really fortunate that my proposal for
> this year Google Summer of Code has been been selected.
> My goal for this summer is to set up a website similar to Panopticlick
> or AmIUnique that will collect data to improve Tor fingerprinting
> defenses. The collected data will be used to detect if there are
> differences between browsers that could ultimately lead to a user's
> identification. With that knowledge, developers will be able to patch
> the Tor browser to prevent leak of identifiable information and
> reinforce the anonymity of Tor users. I also plan to add details on
> browser fingerprinting for users who are not familiar with the subject
> so that they may learn about its mechanisms and the potential dangers
> linked to it. I'll also try to implement a page where Tor users can see
> how far they are from an "acceptable" fingerprint so that they may tweak
> their browser in order to have a fingerprint that is shared by many more
> users.
> I'll officially start coding at the end of May but in the mean time,
> I'll familiarize myself with the Django framework that I plan to use and
> I'll lock down the exact set of features that I'll include in the very
> first version of the project.
> My primary mentor is Georg and my secondary mentors are Gunes and
> Nicolas. I'll post bi-weekly reports to the tor-dev mailing list and to
> my blog to inform everyone of my progress.
> If you have any questions about the project, don't hesitate to ask me.
> The name of the project has not been found yet so feel free to send me
> any suggestions that you may have. You can reach me here or on IRC where
