Virtually all internet cafe's here prohibit downloading anything, and there is no way to get it from computer to you anyway.

A year or two ago I needed to get a driver, took the bloke about 20 minutes to unblock a machine for me, (after 10 minutes of convincing him all I wanted was a driver), then he stood there watched what I downloaded, copied it across his network, burnt it to a CD for me from his office computer, and reblocked the cafe computer.

Obviously Mexican businessman are much more easy going that Australian ones!
