New description:

 As a defense against Website Traffic Fingerprinting, we should implement a
 tunable cover traffic defense that we could set from the consensus with a
 value dependent upon available Guard bandwidth relative to Exit capacity.

 My favorite from the research literature is
 http://freehaven.net/anonbib/cache/ShWa-Timing06.pdf, because it appears
 to be tunable in this fashion.

 The "BUFLO" variant proposed by this paper is better specified, but it's
 not clear it actually performs better for a given overhead quantity:
 http://www.cs.sunysb.edu/~xcai/fp.pdf

 This is likely a research task. People who attempt it should also read
 http://ksubrick.ist.psu.edu/viewdoc/summary?doi=10.1.1.1.8982 (Direct
 link, since citeseer is often down:
 http://www.raid-symposium.org/raid99/PAPERS/Axelsson.pdf)
