I wonder what happens if you set the "Expiration Date" on a data set... Does it delete itself? Require special flags to access? Throw an error every time the data is accessed? Prevent writing? Can you imagine someone putting in an expiration date a decade in the future and it goes unnoticed until it hits? And presumably, like the other options, it can't be modified after you create the data set.
What a truly frightening option to have on a server file system.
