JavaONE...and sleeping is optional

John Gage said at the keynote: "sleeping is optional", but this is not the whole truth. At the JavaONE not only sleeping, but also eating and drinking are optional.
The problem here - too many interesting (and parallel...) sessions at once. And the worst thing are the late BOF-sessions. Because they are even more interesting - the nights are getting shorter and shorter - and you have still a bad feeling that you missed something...

I'm already looking forward for the JavaONE 2008 :-). . ..and I've a SunSpot and some ideas what to do with that...
