Foundry use

Hi guys!

Is there a way to make use of foundry.php outside of joomla environment?
i have a script i made that takes easysocial users and some specific profile fields and puts them into a json file to use for other reasons.

I either want to call this script when the user updates their profile (cant find what view does that tho)
OR
schedule to run that script with a cronjob.
the script cant access foundry.php outside of the joomla environment tho.

Thanks for any advice!
