For what it's worth, I suspect it will be almost as has hard to settle
on an audio codec as it has been to settle on a video codec. Why speex
instead of vorbis for example. If WebM is a success it seems like
vorbis in a WebM container would make a lot of sense.

But yes, if you can get all vendors major browser vendors, one of
which is not on this list, to agree on a codec and container format
for audio, then that would be great. I suspect mozilla would be
willing to support it, though I can only speak for myself and not the
rest of the mozilla project.
