Section 2.1 says: "The timestamp (from the RTP header) to within a few seconds. With a typical 100 ticks/second clock, this represents about 10 bits of entropy at most (and potentially more like 2-3 bits)". The RTP timestamp has a random initial value, and typically ticks at either 8kHz or 90kHz. It's not a wall clock. There's more entropy here than supposed. -- Colin Perkins http://csperkins.org/
