Well, I must admit I've never tried anything like this myself, but I would think that it's just a question of the right user and file permissions. At least in Linux. I have no idea how Windows servers handles something like this, but I'd believe something similar would be possible.
Edit: And of course I didn't think of rented servers either. Hosting my own server has made me a little blind. Now I do see the problem more clearly.
