I'm supportive of the proposed process of, basically, "have a PR by
September if you want it in 1.0".  I like how it's is a clear definition of
what we need to look at in September, and gives us all impetus to get
things done by a certain time.

By the way, I plan on getting out PRs for the following soon, certainly
before September:

RtpSender/RtpReceiever.getCapabilities (had good consensus at TPAC 2014)

RtpEncodingParameters.maxBitrate (not as clear consensus, but lots of
people mentioned the need at TPAC 2014)

RtpSenderInit (has rough consensus on the list)
SctpTransport (had rough consensus at TPAC 2014, and on the list in Nov
2014)
