More on disk images

[ffutures]

Further to yesterday's poll, has anyone tried using Amazon's "Simple Storage Service" for something like disk images? It looks to be pretty cheap, with the charges calculated according to usage, not a pre-arranged plan. So say I uploaded two 500mb disk images, there would be a small monthly storage fee, and a charge each time one is downloaded - I would be able to give registered users unique links to download them.

It sounds pretty good, but the guy who mentioned this was using it for his own storage and wasn't giving keys to other people. I have no idea how easy it is to use in practice.
