Infinispan's been fortunate enough to have Pete Muir - of Seam, Weld and the JSR-299/CDI spec fame - join us. More details are on Pete's blog on the subject. Pete's work on Seam has been legendary, with particular regard to fostering and encouraging a very active community, while at the same time pushing the boundaries of Java EE. With Pete's interest in distributed NoSQL databases and in-memory data grids, expect to see the same on Infinspan!
Welcome aboard, Pete - we're all very excited to have you on board! :-)
