Yes, you can have e2e encryption videoconferencing with large groups of people - just not using webrtc (unless you do some crazy hacks - mentioned in my other comment). By definition, a transcoding server or supernode (acting as an MCU - Multipoint Conferencing Unit) would be a MITM, so that wouldnt be e2e encrypted. A simple way with WebRTC for a small conference, would be to transcode on the origin and provide multiple streams to peers - one for thumbnails, one for higher quality, low bandwidth fallbacks, etc. This doesnt scale well, but it works nicely for small conferences.
