Amazon S3, now for the masses. Amazon S3 has been discussed previously, but several user-facing services have appeared in the last few weeks that allow ordinary non-programmer end users to take advantage of it. One of the most useful of these appears to be Jungle Disk, a free front-end (free beer!) that lets you use S3 as a webdav-mounted disk drive. It works on Windows, Mac, and Linux, and there's GPL code available (free speech!) that lets other people develop alternative compatible front-ends.
