For the record: Jan-Jaap and I are working on this. As a small addendum on 
bullet two: we will actually put an extends-cache directive in the 
buildout.cfg file of the newly created project. The versions.cfg on 
releaseinfo/[version]/versions.cfg will itself extend from the groktoolkit 
and the zopetoolkit.
