The stream echo application is much simpler than the SFU, as it only has to do basic renegotiation/mapping. The code that the SFU relies upon is more complex as it has to keep track of the different streams and their mappings across all of the channels. This was done with a single source in mind, and the mapping process (and stream names) reflect that. I don't think the code will work out of the box, and until someone dives in there's no telling what needs to be really changed.<br>
