Realtime with PubSubHubbub

Question

I'm trying to implement real time chat engine with PubSubHubbub as the core in Rails. My question is what I need to do to or read to achieve this task ? Where I'm gonna start ? What knowledge do I need to know first because I'm really really newbie in this field and like to play with it... or are they any realtime chat engine that is fully compatible with Rails other than pshb ?

Thanx

Why don't you check out XMPP there is a good library called XMPP4R. XMPP is what Google IM uses and there are a bunch of existing clients and IM gateways that support it so you'd be able to very rapidly do things like hook up your program to IM you when a certain event happens.

It is my understanding that PubSubHubbub (as a protocol) is designed less for things like chat (1 to 1 communications) and more for situations where you would previously have to poll a resource for updates (like a series of RSS subscriptions).
