Hey Gary, Very cool to be hearing from the Launchpad project! Am I correct in that lazr.delegates implements a form of the decorator pattern? If so it'd be good if the documentation mentioned this somewhere. I know that Launchpad's use of Zope 3 has been evolving in its own direction for a while, and it'd be interesting to learn more about how. I'd like Zope to be informed by Launchpad's experiences. Things I know from hearing a thing or two over the last years is that Launchpad uses a relational database as its backend, with at least Storm planned for this (whether the transition has been completed, I don't know). I also know that template designers have various convenience adapters available to them within ZPT. There must be much more, however. I'd also like to know which Zope 3 libraries Launchpad currently uses (and what versions), and whether any libraries have been replaced or forked, and so on. Regards, Martijn
