@ArneBab @davep @yawnbox Note that in the specific use case of Signal: given their threat model, "direct peer-to-peer connections by default" are not desirable. You'll need to bounce the audio&video traffic by default to make it more costly to infere who is talking with whom.
So the fact that working NAT and IPv6 help rely less on TURN servers won't help decentralize that much.

@dryak Maybe a start could be to switch to direct peer-to-peer connection if Signal sees that both sides are in the same subnet (i.e. on the same wifi). In that case they connect to the signal server for connection with a voice-data profile *at the same time* which already gives away that they are talking, so staying in the subnet with a direct peer-to-peer connection would reduce the total privacy loss. @davep @yawnbox
