More about digi-pak at http://www.digipak.com/ - looks like an interesting and versatile packaging format. It's not clear whether the standard jewel case equivalent digi-pak has a spine (edge) panel for printing on, so you can identify them when they are all in a rack. Also I assume that it will fit in jewel case rack slots.

Anyone using DVD cases? The disc is exactly the same size as a CD of course, but there's far more room for printed info if you need that.
