Re: [codec] Next Steps for WG

Hi Roman,

We believe that we meet all requirements that were identified. As for 
mixing multiple encoded streams, that was marked as desirable in the 
draft because it's very hard to achieve without sacrificing efficiency. 
To some extent, if you constrain the Opus encoder to a subset of the 
available options (CELT only without short blocks or post-filter), then 
you can create streams that can be mixed at roughly half the normal 
complexity. I think that's about as much as we can do here.

Cheers,

	Jean-Marc
