That's why I try to put a little more light on that...

It's based on H.261, which is known very well and whose patent window

Not? What's about

That's why I try to put a little bit more light on this attempt: to  
raise the attention of the HTML WG (I wouldn't deny its role as a  
standards body) also to OMS video and to not lose track of OMS video  
besides the other alternatives.

Maybe Sun's attempt with OMS video deserves a little bit more  
attention than it does yet? Maybe OMS video could benefit, if  
attention is raised, if people and industry contribute to OMS video  
specification and implementation, to make it better and to start  
implementations at all? Maybe.

That's why I try to promote for not losing sight of OMS video (and  
possibly engage more actively in its development and improvement as  
happened lately with Theora) as a possible alternative besides the two  
widely discussed favorite candidates Theora and H.264. It could be  
worth the try, couldn't it?
