I think the python scripting with embedded data is worth a try. I'm not familiar with the built-in vs other server modes so I'm not sure what kind of restrictions that entails. Probably my ultimate goal is to build a reader plugin that will parse the data out of my application's native format but generating a script seems like a decent interim solution.
