I have updated the Stats proposal to include a few more stats that the 
Chrome team has found necessary and/or useful to their work.

The proposal is at https://www.w3.org/2011/04/webrtc/wiki/Stats

Changes include:

- Added counters for FIR, PLI, NACK and SLI
- Added a "packets lost" counter
- Added "target bitrate" for an SSRC
- Added RTT on a SSRC (RFC 3550 computation)
- Added audio level, Echo Return Loss and Echo Return Loss enhancement 
to a MediaStreamTrack
- Added certificate information
- Added RTT, bytes sent, bytes received, available outgoing and incoming 
bitrates to a candidate pair

With these changes, I believe we have a reasonably complete set of stats 
for version 1.

Questions for the WG (apart from the obvious "are these well defined, 
necessary and sufficient"):

- Should this be a separate document? (I believe yes)
- Do we need an IANA registry for later stats, or should we go with 
"living document" approaches?

Enjoy!
