This is a good option. To be a little more concrete about it.
In your python (or psp) file loaded by mod_python you can do:

from mod_python import apache
yourmodule=apache.import_module("yourmodule",1)

This will only reload (and compile) your module
when it changes on disk. So yourmodule.py could
automatically be updated when the data is changed
(with a timestamp for e.g.) and python would do
the synchronisation automatically.

File encryption

gpg -c file  #encrypts file
gpg file.gpg #decrypts file

Vim has builtin encryption (simple like pkzip).
Use ':X' to encrypt your file. Enter a blank
password to save a decrypted copy again.
