Bitcoin Dispensing Machine

I was thinking about the apparent difficulty people have in obtaining Bitcoins, particularly people who are new to the currency, and also the idea of getting more people involved in Bitcoin.
I had this idea for a "Bitcoin dispenser". Basically a small computer (Raspberry Pi?) with a small LED/LCD display, a coin/notes slot and a thermal printer, like a receipt printer for example.
It displays the current exchange rate, and you put coins/notes in, the display shows you how much BTC you'll get for that amount. Press a button, and the printer prints a paper wallet and transfers the funds to it.
I just can't see major stores accepting these any time soon, not sure if the profits would be high enough... but they could start out in hackspaces and other places? Would need to physically secure them obviously.
