Even if it were, on well-designed systems the temp folder will be 
cleared on boot; on less well designed systems it'll be cleared under 
circumstances your program may not be able to predict; in all cases the 
data has no assurance of survival between sessions.

If the admins have locked down the Preferences folder or equivalent, 
they've set it up to prevent user-specific data writes.  If so, writing 
anywhere will be risky once they figure out they didn't do a complete 
job and then nix the method you'd come up with.

Any chance they can tell you what they want?

Or use a network store?
