Hi Pierre, on first glance looks like a nice proposal. Just a heads up though that to be considered there needs to be a prospective mentor for this project. Reaching out to tor-dev@ is a great first step and hopefully it'll do the trick, but if it doesn't try asking on the #tor-dev irc channel.
Oops, my bad. Missed that this was Panopticlick - gave GeKo a nudge to take a peek. :)
