effectively you are relying on SimpleDocTemplate to write into the response;
according to my understanding that should work. However, without knowing what
the error is makes it hard to figure out what mod_python is whining about. Have
you looked in the apache error logs to see if there's anything obvious going on.
A few years ago when we started with django we used mod_python, but several
things put us off. Firstly we had problems related to tight binding of
apache/python/os etc etc and thene teher were issues about separation of virtual
hosts; at one pint we used a two layer scheme with the VMs on the top layer
passing to individual apaches running the applications with a mod_python for each.
We eventually switched to fastcgi using flup. That has proved very flexible and
stable and allows us to use different versions of django python etc etc.
