Global views for multiple applications

[eluser]zeratool[/eluser]
Here is the scenario:

I have multiple applications and I want to have a universal model just like i did in libraries;

system/libraries/MY_Custom_Library.php

- here my MY_Custom_Library.php is accessible and can be use by my 2 apps

DOCROOT/firstapp
DOCROOT/secondapp

this is working properly, my question is can we have like this for the model?

system/model/My_Custom_Model.php

so My_Custom_Model.php will be accessible by the 2 apps.

thanks a lot and more power to COdeIgniter
