Is there a way to automatically close down an office document

[SkyDog]

I don't know of anything off the shelf that'll do that, but I suppose it's possible to script something. Closing (or killing) the application is easy enough, but it might take a little creativity for estimating/assuming idle time.

If I had to do it with the tools I currently have available to me, I could set up access to the document only through a terminal session (Citrix or TS) and then disconnect or log off the terminal session after a period of inactivity.
