Is it a good idea to implement chatroom like functionality via pubsubhub

Actually I want something between chatro开发者_如何转开发om and stackoverflow ie users can ask questions and in my application generally many users will be on the same webpage now others can see the question in realtime and answer the same in realtime ie kind of chatroom type app.

I want to implement it via pubsubhub any suggestions ideas if this is a good idea or not.

Any java system having this functionality will be helpful.

Thanks Saurabh

I think You can use IRC (Internet Chat Relay ) here for that..

Seems like a perfect match for comet. Pubsubhubbub is better suited for near-realtime server-to-server kinda things.
