Well my original plan was to dual license QtRuby, exactly like PyQt is dual licensed, and offer both a GPL and a paid for commercial version. But I haven't got the impression that there would be a critical mass of commercial users yet to make that worth while. Another problem is that it is difficult to release a Ruby program without source code at the moment, although there have been discussions on this forum in the past about how to do that. The QtRuby code is copyrighted by a small number of people, and it would certainly be possible to add another license type, such as commercial, bsd or mit. If you really do think you need a commercial license please email me to discuss. Note that it wouldn't be possible to release QtRuby under an LGPL license though. -- Richard
