Here's what we are thinking - lets get together and either hack on some projects together or do some focused learning on some topics? I'm thinking breaking out into small groups focused on a topic - BPM / Rules, TorqueBox (Ruby on JBoss), OpenShift, Data Federation, CDI, Mobile, Security...etc - and we go through some mini labs together. Maybe start mid-day and go early evening? That way you can tell work it is training?
Thoughts? What would you like to learn or lead in those breakouts?
