[Zope] one time downloads

Hey fellow zope fiends. I've got a little project I'm working on that involves setting up multiple one-time downloads. I'm curious if anyone out there has done something similar that would like to share ideas and or code. My concept was to have all the files in a secure directory somewhere. Make a temporary directory somewhere with a random id "oahnw3487cfyawcry7baw385vbyawy348vyaw" or whatever... Set the directory name and a flag into a db somewhere. Then after the download is complete (or after a certain amount of time, delete the dir and the files. Anyone have something like this already?
