I'm trying to paint a picture of caching alternatives, and JBossCache looks interesting, especially for cluster scale usage. And the price is attractive compared to Tangosol Coherence.

JBossCache is somewhat new on the scene -- the kit has some nice docs and tutorial/example program, which makes a good impression. I'm curious though if people have any real-world experience with it yet... the bleeding edge is fun, but only if you have blood to spare...

thx
