Hi Flemming, 
I am still willing to continue and complete this work. 
Gonzalo and I had tried to reach out to Hadriel numerous times to better understand his review remarks but unfortunately without success. 
PS: Btw, the "significant concerns", as you called them, came from one person, Hadriel.

Betreff: [MMUSIC] What should we do with the middleboxes draft (draft-ietf-mmusic-media-path-middleboxes) ?
Greetings MMUSIC

As noted previously (" target="_blank" rel="nofollow">, we currently have a milestone for " Considerations for using SDP offer/answer with middleboxes" and we have a WG draft for that in the form of" target="_blank" rel="nofollow">

When we polled for interest in this work about 1 year ago (per the above thread), there was some indication of continued interest in the work, however there were also some (significant) concerns expressed with the draft itself (see e.g. most recent thread in" target="_blank" rel="nofollow"> These concerns have existed for well over a year and we have seen very little discussion or active work trying to resolve them.

In lieu of the above, the chairs would like to ask the WG participants to

1) Indicate if you are in favor of continuing this work.

2) If you are willing to actively contribute to the work by either
a) Sign on as co-author, drive the open issues to resolution, and update the document accordingly
b) Actively contribute to discussion and resolution of open issues in the draft.

Please note, that if you answer "yes" to 2a or 2b, then you should assume that you *will* get called upon to deliver on that.

Also please note, that if we do not get sufficient positive responses to both 1 and 2 above, then our plan is to remove the milestone and abandon the WG draft.
