using views from a themes folder

[eluser]Michael;[/eluser]
Good morning folks,

I am currently working a project that has a three different applications running on the same site, so currently I have as follows:

-> /system
-> /default
-> /admin
-> /meddata
-> /public_html
-> -> /themes
-> -> /images
-> -> /js
-> -> index.php
-> -> admin.php
-> -> mdata.php

We have everything working so long as we put themes and all related view files in the views folder of each application, however, that means we are duplicating a lot of code at the moment as everything changes a bit from one theme to the next. Having 3 themes at the moment, and potentially more in the future, dictates that we should find a way to do this ASAP.

I've done a forum search and cannot figure out a way thus far to load views from outside the application folder. Has anyone else figured out a way to do this?

Thanks everyone.
