Hazelcast

I remember using hazelcast a few years ago when it first showed up. It was great, you still needed to perform some heavy lifting but you could basically implement a headless cluster with the opensource library. This included encrypting the node to node communication and implementing any security model you wanted. Fast-forward four years and there's almost nothing you can do without the enterprise license. When you take some basic features from previous versions, such as security and replication, and wrap them up up behind a pay wall is that still opensource? Maybe I just missed when they started out they were putting out into the world something that could be readily built upon. I guess the need to get those per node and per GB license fees was too much.
