Attached is a *very* simple demo of a blog demo I wrote using PMVC Python and Google App Engine. This was more or less a proof of concept/test to see how PureMVC could integrate with the framework. I don't have a hosting account under App Engine yet, but you can download App Engine yourself and run the demo locally. Instructions on how to do so are in the install.txt file in the zip.
Right now it only includes basic post functionality and a home page that shows all posts. Also, undocumented right now but I will come back and fix that on the next update.
If you can understand the uncommented code, I'd certainly appreciate feedback on my integration here.
