[mod_python] importing from a PSP file

I do what Lee outlines, only I use the default behaviour with a single 
user per VirtualHost arrangement.

Assuming the DocumentRoot is /var/www/domain/site, I extend the path for 
that VirtualHost with this line in http.conf:

  PythonPath "sys.path + ['/var/www/domain/python']"

Now the user/host has a private package repository that is outside the 
DocumentRoot, which also helps to secure sensitive data (in a somewhat 
limited sense). If you are able to use VirtualHosts, there is no reason 
that prevents you from designating a /home/user/public_html directory as 
the DocumentRoot. Keep in mind that the /home/user/python directory will 
need the same type of world-readable permissions in order to work 
(Therein lies the security limitation: other system users will be able 
to read the files. Nonetheless it does offer advantages in a controlled 
environment).
