I have a vague recollection of having problems with it back when I tried to use it for something that sounds similar (I wanted to use it to isolate changes made by a build or packaging system from the underlying OS). I don't recall why I ended up stopping that experiment, though. Since you're already using disk images, though - maybe you can use a shadowfile to get one layer of image combining? -- Daniel J. Luke
