[George Kadianakis]

Hello,

here is the November 2015 report for SponsorR:

- Continued development on the shared randomness project (prop250).

  Lots of new code was written, and various discussions took place in the
  mailing list:

   https://lists.torproject.org/pipermail/tor-dev/2015-November/009842.html

- Discussed potential tweaks to prop224 that would make next generation hidden
  services more resistant to HSDir DoS attacks:

- Almost finished with implementation of the non-anonymous "Rendezvous Single
  Onion Services" RSOS mode for hidden services. People are already testing the
  feature and it seems to work fine so far.

  Further discussion on non-anonymous hidden service modes took place here:

- Prepared some graphs that try to calculate the unused traffic capacity of the
  Tor network, both for hidden services and normal exit traffic:
