I think that its's important that we at least acknowledge the possibility 
that user agents use image analysis techniques, and certainly that we 
explicitly allow the use of such techniques. Even a straightforward OCR of 
many images with no alternative text would dramatically improve the 
accessibility of many pages.

I don't really understand what the problem with the sentence in the spec 
now is. If anything, I'd say the text is a bit weak - given recent 
advances in image analysis techniques (e.g. as seen in Google Goggles), we 
might in fact want to consider changing the "may" to a "should". I do not 
at all buy the assertion that Google is somehow uniquely positioned to 
perform image analysis -- there are open source OCR packages available 
that can target decade-old hardware that perform quite well.

It has been argued that this implementor-targetted sentence might in some 
way counter the pages and pages of detailed author-targetted text that the 
spec has encouraging, nay, requiring, that authors include alt="" text. I 
do not believe this to be the case, but would be happy to include further 
text in the spec admonishing thinking such thoughts.

HTH,
