Hello and thanks for your interest. We are currently thinking really hard about the best way to continue to make our products available as both open source and using an alternative license for those who wish to pay for commercial support. Since donations to K-Int don't begin to cover the cost of running the company we are dependent upon the income stream generated from alternate licensing. However, accepting code fragments under the GPL for inclusion in our toolkits would cause us a problem in this regard. Of course you are free to take the source code and modify / distribute it as you see fit, but we would rather just maintain one version of the code. All that said, we really, really, really want your support, feedback and contributions to any of our projects. Please use the contact form to chat with us about the issues and get working together.
