If you look really hard at www.oreilly.com, no keep scrolling down and down, you will see that OSCON is this week in Portland, Oregon. I don't know if O'Reilly are trying to keep it a secret but they have the who's who of exhibitors and speakers all in one place.
I'll be working on the show floor, flying out today so will be able to send some reports. I plan to meet up with some folks while I'm there. However if you just want to talk Java I'll be more than happy to lend an ear.
