Zeus is willing to provide development licenses at no cost to anyone wishing to build applications that can use Zeus Traffic Manager's load balancing and traffic management capabilities.
The Development Licenses give access to all of the capabilities of Zeus Traffic Manager, including TrafficScript and Java Extensions, and can be used for non-production purposes, such as dev, test, proof-of-concept or demonstrations.
Support for Development Licenses is provided through the Zeus Developer Support forum.
For more information, take a look at the Development License overview document.
