That was the heavy hitter. jen is still right that simplicity and ease of use are incredibly important. Especially that forcing anyone to work with server IP's, ports, and firewalls leads to instant negative reaction. Gotta make that disappear somehow.
Fortunately, there's a lot of schemes to do that with untrusted 3rd parties. Need more work and polish w/ OSS implementations.
