Yes, it uses a lot of techniques I'm well familiar with, techniques that don't really work anymore.  Like STUN.  Mobile networks especially, you're just gonna end up sending all that traffic through a turn relay (which is fine).

 as p2p apps become popular incompatible shit 'networks' will face tremendous pressure to become proper networks 

 I wish.  A majority of the world is on a mobile carriers network..  I just don't see how it would apply any pressure, can't even get people to use a desktop browser anymore. 

 many mobile networks work p2p, mobiles also have wifi, starlink lol

there will be nsa datacenter peers to use, its what american tax victims pay for
