Lately we have been getting feedback from users of our open source product, MantaRay, saying that our open-source license is not very business friendly. Our product is a serverless messaging middleware, in other words MantaRay is a JMS provider. Applications import our manta.jar and work with it as if they had a messaging server (broker) while actually they are working purely peer-2-peer. All the logic that was in the server is distributed and embedded in the edge applications.
