I have a conversation with Volker about the FET license. I would prefer to keep GNU GPL (and upgrade to GPL v3 or later). Volker wants to switch to GNU Affero GPL (AGPL): https://www.gnu.org/licenses/agpl.html
AGPL is for network applications, so that if someone uses FET over a network and makes changes to the FET code, he must provide the source code to the public.
Please let us know your opinion! Let us comment on this!
I think that every contributions to the code/interface should be released, network type or not. So, I am not a lawer and I do not know every implications of GPL, LGPL, AGPL and so on licenses, then If the project stays free and open source is welcome.

Your first sentence is absolutely correct. That is way we already changed to AGPL.
Your second sentence is pretty vague. Maybe for a user it look like all 3 licenses fulfil your request. But for a developer there a pretty much difference in that licenses. Depending on what you understand under the word "free", for a developer "free" and "open source" even contradict in these licenses. A user might think that it wouldn't effect him, but it will effect him (later), since development might slow down pretty much. But as I can see from your first sentences: you are aware of that.
I think that every change that someone makes should be provided and open source and free to use.
As long as who made this code first wants to keep it free and open source, I think it should remain so in any change that is made on it.
Which license to use, I do not know..
