If the goal is to support more devices, then Ogg Theora is not the  
most pragmatic choice. Nor is an optional requirement that many  
vendors are not planning to comply with. So by your argument the  
SHOULD clause is not doing its job.

Given that, it does make some sense to remove it and replace it with  
an open issue marker. Though I do not think we need to hold FPWD for  
this.


One piece of interesting info: Nokia's position paper for the upcoming  
Video on the Web workshop at <http://www.w3.org/2007/08/video/positions/Nokia.pdf 
 > mentions that H.261 is old enough that any possible patents must be  
expired, and that it achieves performance close to Ogg Theora. I don't  
know if the performance claim factually true, but if so it may make a  
better choice for baseline codec. There may be other alternatives as  
well.

I think it would be best for us to wait for the W3C to perform  
suitable investigations on audio and video codecs before coming to a  
final settlement on this point.
