That is hardly a scientific comparison.

And again, it is misleading to imply that I am advocating the mass-use 
of H.261. I am only advocating the use of this codec in the 5-10% of 
cases where the clients fail to agree on a common upgrade path (to VP8 
or H.264). In those cases, I'd happily accept H.261 instead of dropping 
the call. You can still transcode, if you so wish.
