Right, which means that Jon's comments about the licensing being unclear were justified. There's no way for an external developer to verify the license state. The README you keep referring to explicitly instructs the reader to refer to an unavailable document for further information. For many practical purposes, the code is not available under an open license and won't be until it's merged into AOO - and even then, if there are features you're uninterested in (either because they're too niche to be worth supporting, or duplicate other existing functionality or whatever) that code may never be available under an explicitly free license.
But ok. Let's put this another way. If I provided a patch that added a new document to the top level of the symphony svn tree, containing a list of files that the existing README implied were available under liberal terms and explicitly indicating that (barring accidental inclusion of third party code) these files could be redistributed under those terms, could that be merged?
