Looks like we have enough consensus. The people who so far opposed to a license change seem to be in favor of this change. As soon as I can fix the open issues I will change the license for 1.91.1 to LPGL3 and, after that do, I do not want to hear anything any more about the license.
Perhaps I should add a new exception: "you loose the license to use web2py if you complain about web2py or its license". ;-) Massimo
