How realistic is that statement? Today I think I can get 720p (or was it 
1080p, I forget) using VP8 in 1.5Mbps.

How much bandwidth would you need to do the same in H.261? What 
resolution would get you for 1.5Mbps? We need some reasonable comparisons.

I think you're exaggerating how bad H.261 is and it's also misleading to 
imply that the vast majority of users would be forced to use H.261. We 
are talking about H.261 as a fallback (if upgrading to VP8 or H.264 
fails). In the 5-10% of cases this happens, I am advocating we get using 
H.261 instead of dropping the call.
