EvoGUI is now free!Yes, you can use it in any way you like, commercial products included, and you don't need to share any modifications you make etc.
I have not changed the text of the licence on the download site and within the download itself, but as of today you can feel free to disregard it. I surely won't change my mind again, so you don't need to worry. I will change it officially to GPL or something similiar in the near future - if anyone really cares about the official texts more than my word.

I have also made several improvements since the last public release, but I will release the new version only once I have added a few more features. It will be in 3-6 months from now, depending on how i order my working schedule as I am working on more important parts of my project right now. Once that is released, I will also create the SVN.
As far as support goes, you can ask questions and I will usually answer them if/when I get the time. So far most questions about functionality have been addressed and I've added/changed some features as a result.
One user also ported it to C# so if anyone needs this port, let me know and I will upload it.
Cheers
