After the Olympics someone should buy up these machines and modify them to print Bitcoin vouchers.
Place them in malls, recruit some stores to accept bitcoin and print store names on back of vouchers.
Maybe Bitcoin Foundation or one of the major bitcoin businesses looking for publicity could sponsor - because VISA sure won't do it.

Saw those machines on the news a while back, but are you sure they can be modified that easily?
It's not a big stretch - just dispensing value on a piece of paper.
It looks like the value is printed at time it is dispensed. If it is inkjet technology then it would be easy to print a bitcoin value w/QR code. The machine would check with a server to determine exchange rate, etc.
If it is a different technology then it would probably require a retrofit with thermal-printed slips instead of card stock. Preprinted vouchers would be too risky.
Yeh, somebody could hack this out, but it would probably be easier to work with the manufacture to modify the existing system.
