Interesting idea .. will all the files be made available under the same URL?
You're gonna have to take care of
*) Some place to store the files
*) Some method of holding the restrictions
*) A way to retrieve the restrictions
*) Some effort to serve the right file at the right time

Simplest would be one perl script, connecting to a database, looking up
which file is valid for this time, open that file with perl's file handling
methods and putting it back to the browser. Pretty straightforward.

Depending on how many times you'd be re-using the same file, it might be
easier/better/more fun to:
*) use the filename to hold the restrictions (ie:
secrets-200407121100-200407121800.txt for a file valid from 7 jul 2004 11:00
till 18:00 of the same day)
*) write a handler that serves the wanted file on a request

That's about all for my general suggestions at this midnighty hour.. Maybe
I'll have more tomorrow, hopefully after a reaction of your own :P
