automating export of iCal files based on user settings

I love your product and it appears to be the soloution I am looking for, however...
Is it possible to allow users to remotely export personalized iCal files that can be viewed via PHP iCalendar ? huh?
Let me try that again...
I need to allow multiple users to dynamically generate their personal calendar so that it is created by the user and requires no admin help/work from the FileMaker DB admin. this would require many users (>100) to have their own accounts that pull appointments from one master appointment file that is updated by the admin.
my other question is ... would you suggest having seperate layouts that pertain to different security levels or should they be relational DBs to enhance security?
thank you for your time and assistance
