yes, but maybe we need a pragmatic solution for the moment, the
share-alike CC-licenses, the BSD documentation license, or the GNU free
documentation license may be good starting points.

Yes.

While I agree with all the statements about community based development with Sourceforge, I must say that this approach has been tried unsuccessfully in different sets of activities that I have been participating in the past. The main problem with this is the following: source versioning systems are focused on detecting changes/deltas in source code, but not in ontology code. When a person makes a change in an ontology with an ontology editor, the most important fact is that the serialization of the ontology may be **completely different** to the previous one, in terms of the ordering of the RDF triples that appear in the file, what makes tracking of changes almost impossible for humans.
