>> In most cases, the public ip candidates given by STUN servers are
sufficient for peers to negotiate a working p2p path. But sometimes, maybe
14% of the time [1], this isn't enough -- usually due to symmetric NAT /
lack of port preservation, and a TURN relay is required as a last resort.
>>
>> Also, once snowflake proxies & clients are multiplexed, perhaps the
likelihood that TURN continuous to be absolutely required for every pair
of peers greatly decreases and we might be fine again. More thought is
needed here.
