here is the December 2014 report for SponsorR:

- In the beginning of December we revised the hidden service
  statistics proposal [0].  We also implemented the statistics in tor
  and after asking for review and feedback from the community we got
  the code merged upstream. The code has since been released as

  We then asked volunteers to run our code on their relays. In just a
  few days we had over 70 relays submitting hidden service statistics
  which gave us a data set that could be analyzed.

  Finally, we started the analysis of the data by writing a
  document [1] that details our findings and tries to extrapolate from
  our limited dataset to the whole Tor network.

- We revised the tech report that enumerates the various hidden
  service statistics [2]. It's currently still a draft and will likely
  be improved further in the following months.

- Aaron Johnson started a [tor-dev] thread [3] with some ideas on protocols
  that allow better and more accurate statistics collection while
  preserving the privacy of hidden services.

- David Goulet wrote a post [4] on his technique for benchmarking the
  performance of hidden services. The post includes some interesting
  graphs on the performance of hidden service circuit establishment [5].

- Started work on combining the Shadow simulator with tracing, to
  measure hidden service performance on simulated networks.
