Much less so than comparing "promotion of H.264-in-<video> via
Google's sites and client" to "support for legacy proprietary content
via plugin APIs", I would say.  But also, I didn't compare DailyMotion
to YouTube!  I used it as an example of converting content at scale,
to speak to the relative impact of a codec change vs. API changes in
terms of effort.

I don't think the bandwidth delta is very much with recent (and
format-compatible) improvements to the Theora encoders, if it's even
in H.264's favour any more, but I'd rather get data than share
suppositions.  Can you send me a link to raw video for the clip at
http://www.youtube.com/demo/google_main.mp4?2 so I can get it
converted with the state of the art encoder and we can compare
numbers?

That's great news -- I wasn't able to be at Google I/O, and I can't
find any mention of Youtube providing Theora for consumption anywhere.
Can you clue me in with a link?  (It does seem that Youtube accepts
Theora at upload, but it seems like it gets transcoded to Flash or
whatever at that point, so it's converting from unencumbered to
encumbered!  http://www.youtube.com/watch?v=roE4bmOSURk is one example
that I'm pretty sure was uploaded in Theora format.)

That's indeed a big part of what we've been funding, and the results
have been great already.  I'd like to demonstate them to you, because
I suspect that you'd be a better-armed advocate within Google for
unencumbered video if you could see what it's really capable of now.
(Separate from the Wikimedia grant we also just started funding work
to port Theora to some DSPs, so that we will be able to do off-CPU
decode/yuv2rbg/scale on some devices.)
