Kevin Pollet and I were interviewed by DZone about the CDI support in Infinispan - if you are interested in Infinispan, caching or data-grids, this should be interesting for you.
The CDI support is also a partial implementation of JSR-107 - the temporary caching API for Java that has recently reactivated and published a first draft for review . Greg's blog has more on using JSR-107.
