Make public bridges add obfsproxy stats to their extra-info descriptors
Roger is planning to install obfsproxy on moria, probably pointing to a separate Tor process being a private bridge, and publish its address to get some testers for obfsproxy.
We discussed adding obfsproxy stats to Tor, so that we can keep track of obfsproxy usage over time. However, this requires the extended OR port to be implemented, or Tor wouldn't know much about clients connecting to obfsproxy.
The new obfsproxy stats code would go into Tor 0.2.4.x anyway, but setting up an external proxy is already possible with 0.2.2.x. So, we wouldn't get all statistics anyway.
We could make obfsproxy write some stats to disk and ask people we know to give us those files, but that's probably not worth the effort.
We should discuss adding obfsproxy statistics to 0.2.4.x together with the extended OR port. Once we have that we should distribute images with public bridges running 0.2.4.x, with obfsproxy, and with obfsproxy stats.
