[liberationtech] New Anonymity Network for Short Messages

"the ideal would be to hit a high enough rate that it makes real-time
analysis of content (by a human) impossible. By the time the service hit
that rate of chats, it will be nigh-unusable by people.  "

Every client could broadcast a message on a timer. Sometimes the message
would be wheat and sometimes chaff.

Then the downsides would be:

1) Additional latency between composing the message and the next timer
pulse. In terms of UX, slower sends.

2) A bigger buffer, flushing more often.

Problem #2 could be ameliorated with something like sharding. If there were
S shards and M messages total, a peer would buffer M/S messages.
