Webex devices ideally should support NDI sources and outputs.
Webex devices should be able to output an NDI stream for each video stream they are receiving, the local view and presentation.
Webex device should be able to accept an NDI stream as an input from a camera (or other device)
NDI camera/presentation source will remove the need for HDBaseT transmitter/receiver pairs and sell more network gear!
Cisco cameras should support sending an NDI output to a codec as well. This helps a lot in scenarios where the camera is not near the codec.
I've got several customers that broadcast live events that would love an NDI output from a Cisco Codec to be used for their video mixing gear. This would also allow them to easily send content to the Webex device via NDI.
