[mod_python] I need to create a Zip file on the fly and write it tothe stream without any temp files or in memory file creation?

Can you please explain the .tell() issue and how it is a problem? If
you are packing it into an instance of StringIO rather than onto req,
then it will be able to find a .tell() function and others it needs.
Obviously, the issue with StringIO is that it must hold it all in
memory until everything is complete and only then can you send
data. Ie., can't be streamed as you go.

Thus, please show examples of how you were using ZipFile and go
into more detail of why it doesn't work and what errors you get.
