Talk about existing hosted graph databases, what you like about them, what you would want to have.
How to integrate with them, what kind of drivers are there?
What PaaS to use to run your actual apps (AWS, Heroku, OpenShift, Cloudfoundry, EngineYard, ....).
We would also love to talk about the Neo4j Heroku Add-On challenge. http://neo4j-challenge.heroku.com
We have two special guests tonight, Andreas Kollegger flies in from the US and Peter Neubauer comes from Sweden. So the complete Neo4j Community team is available for your questions and ideas.
