Comment:

 I started some work here as prop280, and gotten some feedback.  Carolin
 Zöbelein has also written some outlines for a Shamir-based protocol.  I've
 taken a shot at a variation of a Shamir-based protocol at
 https://github.com/nmathewson/privcount_shamir , where it appears as a
 python prototype.

 Current open question: does Shamir-style secret sharing actually do
 anything to help with the case where some Data Collectors are misbehaving?
 So far as I can tell, it only really helps us handle malfunctioning Tally
 Reporters.
