Selective media copying

1. UserA owns GMG ServerA.
2. UserA goes to GMG ServerB and sees an image.
3. UserA puts URL of the image into his ServerA.
4. ServerA fetches the image from ServerB with all metadata, so it becomes available at ServerA.

• Access (both viewing and copying) to the image might require authentification.
• The result should (must at least if authentification was required) be marked private by default.
• It should be possible for the result to have a visible reference to its source.
• ServerB may be notified of the copying, so that it can link to the result, if it chooses to (http://bugs.foocorp.net/issues/604).

Another use-case

1. UserA has private ServerA at home (possibly not accessible from outside), and an account at remote ServerB.
2. UserA stores media in ServerA (possibly uploading by copying to a directory), and has the option of uploading all or parts of it to his ServerB account.
