Just a comment: Realtime communications in HTTP is, today, a hack
Don't make me give examples of services with web im/presence for tens and hundreds of millions of users, they worth billions, a reality today. How you call it, up to you.
Not all of us can replicate the infrastructure of Google. Google is capable of serving a single IP and port for every person in the world to connect it, and make it scalable.
There are hundres of web pages offering chat services within the web, but just Gmail (and a few others) work decently. There is more that just specifications and protocols in the Google warden ;)
