I apologize for the ambiguity, the plug-in I’m making is not for Processing, it’s for a commercial software.
As far as I know, LGPL license means that I must keep the core libs open source, but I can restrict the access to the sketch classes/codes, which I write. Am I right?
I think I’ll have to come up with a good way of obfuscation myself. Don’t know where to start, though. A commercial service would also be OK by me if it’s easy to use. Any help would be much appreciated.
