I'm not sure what you want to accomplish here - but one of the nicer aspects
of python is that you don't have to inherit from file when you want to pass
a file-like object to some lib. See the cStringIO module. So if you create
a edi-class that _behaves_ like a file, thats all you need - you then can
pass it to any file-accepting pieco of code.

Is that what you've been asking for?
