Hi,

>As an individual draft or WG draft?

It was meant to be a new version of bundle...

>because I am definitely don't think we have consensus for the "m=bundle" approach yet. I just think the >m=bundle approach is going to be much harder to get to work with existing equipment.

What is the a=bundle approach? Offering "normal" (audio, video, etc) m- lines, and then use one of them for the whole bundle?

Regards,

Christer
