them:

1.     Browsers MUST support both H.264 and VP8, other entities MUST support
at least one of H.264 and VP8

a.     Are you in favor of this option [Yes/No/Acceptable]:

 

RS> Acceptable leaning strongly to YES. 

 

b.     Do you have any objections to this option, if so please summarize
them:

1.     All entities MUST support at least one of H.264 and VP8

a.     Are you in favor of this option [Yes/No/Acceptable]:

1.     All entities MUST support H.261

a.     Are you in favor of this option [Yes/No/Acceptable]:

 

RS> NO

 

b.     Do you have any objections to this option, if so please summarize
them:

 

RS> Not efficient on the wire by any reasonable operational standard.

dooms the entire project.
