So weighted coin rulez! Great.

One more concern: what about inserts? With a simple weighted coin, some data 
will be inserted very shallowly. We won't retry the insert in response to 
failure, because it will succeed. We could send the insert two or three 
times? Weighted coin followed by an HTL countdown would give away more 
information than just weighted coin (although the difference is marginal, 65% 
vs 64% for 10 positive 10 negative vs 20 positive), and privacy is especially 
important for inserts.
