Comment (by teor):

 I attached a modified version that works in Tor Browser 5.0.3 on OS X
 10.10.5.

 It discovers my Microsoft Office installation. It also discovers my
 Wireshark installation.

 This looks like a fingerprint to me, but I don't have multiple machines to
 test it on, so I can't be sure.
