Google provides free STUN server. We can use these to setup a WebRTC data connection between browsers.
To be able to find other participants we need an unpredictable but controllable ID. Could be the hash of a static part like 'ngx-present' and a securely generated 6 digit alpha-numeric. By sharing the generated part (as part of the url or by tipping manually) browsers can open a channel.

Via the WebRTC data connection we can share some part of the internal state. I would prefer to send events not the resulting state. Events like 'navigate to slide 1.2.3'. Maybe we can reuse redux actions.
