No, they haven't. Please try running a web server behind a NAT that you
can't forward ports on. Or ssh. Or any number of other client/server
protocols.

I was thinking of P2P file transfer protocols. Bittorrent, gnutella, fasttrack, etc. Uploading doesn't always work really great, but downloading is quite decent. Bittorrent seems to have zero problems saturating upstream bandwidth on many torrents that are 100% behind NAT. I classified (mentally) freenet as a P2P, but it's more like a server-to-server for best performance.

You always get far more responses if you're forwarding the ports. Quite simply there is no way for two firewalled users to communicate without at least one forwarding ports. All those P2P programs do is restrict you to connecting to users who're not hiding behind a NAT device, and if they want to download a file from you they send a message via the network to open a connection to them.
