EchoStudio will soon be available as an open-source project.
The current thinking is to license EchoStudio under a strong copyleft license, i.e., a modified GPL license with a provision to allow use within the Eclipse environment (required as the GPL can technically otherwise prohibit such use). The idea is that everyone should be able to freely use and contribute to it, but without the ability to commercialize it. I don't want developers to have the ability to cut and paste features into their own Echo-competitive commercial Eclipse plugins, or to make a derivative closed-source commercial version. I'm very open to ideas on the licensing strategy though, please feel free to suggest other license strategies if you think they'd be more appropriate. Please get in any feedback on this front by November 15.
The license of EchoStudio will of course have no bearing on the code which is generated or built using it, your code is your code, subject to whatever license you see fit to use.
