Hi,

Here is a condensed response to the past 200+ posts :)

  * Instant run-off voting
      o I don't think that voting will solve all of the problems
        mentioned below, but if all other options fail (which we're
        close to) then I'm in favor of going ahead with the proposed
        process.
      o Whatever process we agree to should end with a binding decision
        at the end (as opposed to more endless debate).
  * People objecting to the very idea of voting (versus making the
    decision on a technical merit) miss the fact that this is no longer
    a technical debate.
      o We have already agreed that both VP8 and H.264 are technically
        "good enough". The only remaining differences are of a political
        and licensing in nature.
  * Voting will not solve (legitimate) licensing/IPR issues
      o For example, mandating H.264 as MTI won't help Debian because
        they cannot count license units.
      o We should brainstorm on how to remove these show-stoppers for
        all stakeholders (browsers, non-browsers, FOSS, Commercial). The
        "MUST implement 2 out of 3" approach is an example of how this
        can be done.
  * Who should participate
      o Either we should include anyone who posted on WebRTC mailing
        lists (rtcweb, public-webrtc, public-media-capture) or we should
        be try to be more inclusive by including anyone who merely
        subscribed to said lists.
      o As was suggested, publishing the full list of all voters along
        with their votes should remove any doubt of fraud. If we notice
        that 5000 voters came from the same company, we can legitimately
        question whether they are all active or whether they attempted
        to stuff the ballot.
  * Removing voting options
      o I think it is vital that we leave all options on the table
        (however silly some might think they are) and see where the
        chips drop.
      o I understand that some people object to a long list of options,
        but I'd rather err on the side of inclusivity than censorship. :)
  * Non-browsers are equally important
      o Most of the debate on this mailing list have centered around
        what the browsers will do, but if you've attended the WebRTC
        World conference over the past couple of years you will have
        noticed that a great number of demos are based on native
        applications (even more so as mobile adoption increases). There
        is a very strong interest in using WebRTC outside of the browser
        and any decision we make here should reflect that reality.
  * Endless debates aren't free
      o One thing that was evident at the conference is that many of
        companies are "moving beyond the specification".
      o The longer we debate these issues, the more likely we are to end
        up with a specification that simply documents the de-facto
        standard laid out by early adopters.
  * We need a higher-level Native API that mirrors the Javascript API
      o It's become evident that many companies in the conference are
        re-inventing the same wheel: namely, they are reimplementing
        features found in the Javascript API on top of the Native API.
      o Imagine how many developer years could be saved if the Native
        API provided some of these higher-level constructs. This ties
        into my earlier point that "non-browsers are equally important"
        to take into consideration.

     Thank you for the interesting conversation. It was nice meeting 
many of you at the conference! :)
