Porn Buddy Concept

I heard of this concept watching an episode of BBC's Coupling. Although
the concept revolved around porn on the show, it could easily be expanded
to include other things.

The concept is the following:
If I happen to die an untimely death, a buddy of mine would come into my
home (he/she would have a key) and remove any material/information I would
not want my family (or anyone else for that matter) to know about.

Initially the idea was just funny, then I caught myself thinking about it days
afterward and thinking it was a great idea.
FYI: I don't own porn.
