There is a lot of different licenses approved by the FSF as Free Software
License but don't have the same purpose as the Gnu Public Licence. Like for
example the zlib license (I heard of it only yesterday), that is a license
that allows the developer (if I'm not wrong, and please correct me if I am)
to distribute a binary version of the software without releasing the source
code. But that is just an example... Don't know if this really apply as a
Free Software if this particular part of the license is used.
As for your license question, you could specify want you want for your
software and we "could try" to help you with that.
PS: You can still use the WTFPL License (http://sam.zoy.org/wtfpl/). I'm
kidding on this one, but it is fun to see a license that allows you to do..
well... everything you want.
