I can't name a mass market service today that doesn't work through NAT 
and the ones you point out are certainly do.

Playstation Network works, by design, flawlessly through NAT and is 
_not_ a peer to peer application.  All traffic goes to the PSN servers 
and then to clients.  Go2MyPC is designed for NAT and in fact one could 
argue that it wouldn't exist if NAT weren't wide spread.
