I can't help you on your chosen path, but let me emphasise that the code you 
posted looks like it has great potential for speed-up by replacing the inner 
loops with numpy array operations.

If you post a small dataset somewhere and a version of the code that can run 
standalone (no undefined variables or libraries, no commandline arguments) I 
might even tinker with it myself to demonstrate this potential...
