I think the problem is the "non-commercial purposes" statement, which doesn't mesh well with open source licenses. For example, it's OK if someone makes DVDs of Avogadro + sample files and sells that (as long as they also make the source code available).
But that doesn't seem to fit with the non-commercial requirement. In any case, I've compiled a set of almost 100 CIFs from the Crystallographic Open Database. Certainly we can add support for searching/downloading from WebCSD (Pitt has access) and other online resources as well.
