I mean a situation where we can't setup the UDP channel, if one endpoint is for instance in a corporate network from where only HTTP or HTTPS is allowed. So presumably we'd have to support some kind of HTTP or TLS encapsulation/tunneling for the data channel as well, from the endpoint to some kind of relay. But how would the end-to-end data channel look like then? I.e. what would be sent over the tunnel? >-Ekr Markus
