Not wrong, but if you want multiple servers of the same service, you're now doing custom ports (myhost:port1, myhost:port2, etc) which isn't the end of the world, but is kind of sucky.

And if we're not talking just about servers running services, but clients that want to do peer-to-peer stuff, you also have to use things like STUN/TURN/ICE which is more infrastructure that is needed (as opposed to 'just' hole punching since your system already knows its IP(v6) address).

Given the prevalence of these technologies (kludges?) they've kind of been normalized so we think they're "fine".
