CommunityOne is the conference one day before JavaONE - in the same location. It's worth to attend.
Last year's sessions were really interesting. Beyond pure technology there was enough fun as well.
I really enjoyed the JSF / Sun SPOT Session about D.O.R.K (Dog Oral ...) an application which controls a "machine"
which feeds the dog, dependent on it's behavior - it was really funny (was this session actually recorded by someone on video?).
You have still chance to submit abstracts and present a session:
