2) Dissadvantages of using SDP in WebRTC. Roman said:"An unmanageable monster was created which currently stays in the way of developing new functionality (bundle), building applications (does not provide obvious ways to implement obvious tasks, like adding an extra stream without re-negotiating all the existing ones) and even interop with existing SIP endpoints (which was the original but now is complicated since it would require a non trivial set of constraints and subsequent SDP manipulation)." [BA] Hard to argue with this, but I would point out that by far the ugliest part of the monster is the video hindquarters. While one could argue that we have been living with the warts of SDP for audio and therefore know the workarounds, with video there are substantial interoperability issues, *even among vendors who utilize the same codec*, sometimes even in relatively basic scenarios (e.g. P2P video call with H.264/SVC). So the "multivendor legacy of interop" just doesn't exist yet (at least, based on standards). So as I see it, it does represent progress that we have contained the SDP monster's impact on the the data channel, and I welcome Peter's effort to enable applications who don't care about SDP to minimize its usage even if it is not eliminated entirely.
