Re: [MMUSIC] [Ice] Updated charter

["Ben Campbell" <[e-mail]>]

Hi,

If we hope to have ICE approved as a working group in time for Yokohama, 
we would need to start the IESG internal review by this Thursday. IMO, 
this language is about right. I think there's still an open issue about 
where the SDP bit lives. Can we close on that?

Thanks!

Ben.
