It's tragic that this article even needed to be written, but at least the people the author is responding to are aware that wave is a protocol, huh? Baby steps...
No kidding... the Internet was original conceived of being made up of purpose specific protocols. FTP for file transfer, NNTP for chat boards, IRC for real-time chat and so on. It was only with the hacked (over)use of NAT and wide spread deployment of lazily configured (read: over-paranoid) firewalls that this original vision was sidetracked through the HTTP pinhole (and is also hamstringing deployment of IPv6 to boot!)
