Appsembler is a SaaS enablement platform for open source web apps.
From the Appsembler site: "We help developers monetize their software, and make it painless for end users to try their software."
This is the Appsembler main page for developers.
Saw Appsembler via a chain of links. Only checked it out a little so far, but live chatted with one of the founders, Nate Aune. He said it runs on Stackato, the PaaS from ActiveState.
Multiple programming languages and web frameworks are supported, according to Nate, but for Python, only Django is, currently. Also, it works better if you have a Github account for your SaaS app.
Here is a blog post by Nate about Django deployment using PaaS.
