It seems that one of the motivations of the current bundle-03 proposal is that the first offer is compatible with a legacy device and that a second offer is required for bundle (See http://www.ietf.org/proceedings/86/slides/slides-86-mmusic-9.pdf).

One issue that I see is that if TURN is being used there could be a significant overhead in creating the first offer is multiple TURN allocations are needed for each m-line which will all then have to be released if bundle is used.

I am not sure if there is a way to avoid this other but the draft should I think mention this issue.
