Kai and I attended Chris McDonough's talk on buildouts -- in general, not specifically about zc.buildout -- at the Plone Conference. I left motivated to start thinking about buildouts. Kai left motivated to do something about common environments for developing PrimaGIS. His solution is primagis.buildout: a script for making complete, isolated PrimaGIS sandboxes. So far, it's only tested on OS X, Debian, and Ubuntu, but already has several new users up and running. For windows, I imagine we could use more binaries, and try to tap into Howard Butler's build kit for PCL-GDAL and PCL-MapServer.
