Large Deployment Architecture

Are there any resources available that discuss large scale deployments of openfire? I’m specifically looking for information regarding the deployment architecture for a 100,000 to 300,000 user-base. I’ve read some posts on the connection manager and load balancing, etc but would like to hear from the community, especially from someone who has implemented openfire on this scale and what was achieved with what components/hardware.

paulj, did you find any information on a large deployment. If yes, I would appreciate if you could shared with us here. We are looking into a large scale deployment and trying to research what levels can be achieved with OpenFire. Thanks.
