Chat - like live help

Hi all - I have a windows form app in vb.net and also an asp.net site. I was wondering how I would go about letting clients get "live help".

They would log into some kind of chat window and the staff here would be alerted that someone is waiting in the chat room. The staff here would have a chat client (windows form) and would chat live to the client over the internet.

Anyone have any ideas or resources on this type of thing?

TIA again :)

Steve.
