Thats cool! If you do open up that box please take a picture of the inside!
Tried to get it open today to take a shot, but it was screwed in so tight I couldn't manage it.
Thinking about it though, it would be pretty simple to wire up. You'd just need separate jacks for clock input and output... and they obviously couldn't be used at the same time. Could always just have a single jack with a switch too.
