Hi, Martin, Just a couple of thoughts here:

I'm assuming that getting the core QUIC specifications published and doing any cleanup work necessary SHOULD/MUST take priority, in the BCP 14 sense of those words. As Lars' initial note said, I'd also like to see the manageability, applicability, and datagram extension working group drafts, already adopted by QUIC, moving forward. > I don't think the community has well-established solutions for many > problems in this space (e.g. scheduling).

And I agree that the QUIC protocol would be a better platform for experimentation than anything I can think of (other suggestions are, of course, welcome). > IIUC the hard, unsolved problems are common to all MP protocols, so I > don't think further research and future standards in this area are specific > to QUIC or appropriate for the QUIC Working Group.

I know you have a variety of tools at your disposal to direct this work (MP-TCP was done in its own working group, for both Experimental and Standards-Track versions of the protocol specifications). Do the right thing, of course. What do you and Magnus need from members of the community, to help move forward on this?
