pcal on POJOs
I'm giving a talk tomorrow night to the Java SIG on how to cluster your Plain-Old-Java-Objects with Terracotta DSO.
I'm just getting over a nasty cold that laid me flat this weekend, so it should be extra fun. :/
Update: the talk went pretty well. Well-attended, about 75 folks, AFAICT very senior Java architect type guys for the most part. Chris Richardson gave a really good talk on Spring, and fortunately, most people stuck around for my part. Lots of questions - borderline choas, actually. Didn't even make it through my slide deck. Was fun though. GaryN took some photos but didn't get a good one with the crowd in frame. Oh well. I'm really talking to a bunch of people here, honest. :)

Good luck, though I'm sure you won't need it and will do very well!
