Re: [rtcweb] Call for Consensus on Use Case for Screen/Application/Desktop sharing

[Cullen Jennings <[e-mail]>]

I think we should do both and we should do it by using SDP to negotiation a session of VNC as defined in RFC 6143. Given we will have a way of setting up a data channel between endpoints, running RFC 6143 on top of it is trivial and does not add much work or complexity. I would propose this as optional to implement.
