If you're thinking about keeping the taps inside the fridge only temporarily, you could just use cobra taps until you are ready to move it to the outside. If you're talking permanently, though, I can't quite visualize what you would do. One of the nice things about having the taps (which I still don't have!) outside is for convenience and looks. I still have the cobra taps, and have to open the fridge each time, and see the not so attractive lines and kegs. I'm looking forward to drilling my fridge and sticking the taps on the outside, and a drip tray!
