yea.. the take home point is that Theora now has an encoder that puts it 
in the same ballpark as contemporary proprietary codecs. I would not say 
Theora is "outdoing h.264". The results of a given PSNR test are 
impressive and important to publicize but I think my wording in posting 
about that test might have promoted overstating the quality factor.

The only quality that really mattered in terms of standardization has 
stayed constant: which is Ogg Theora is /royalty free/ and implementable 
in both proprietary and free software browsers.
