It may be that things described here are described, and better described, at [[API]]. --[[User:Aleksejrs|Aleksejrs]] 15:44, 8 November 2011 (EST)

== Selective media copying ==

# UserA owns GMG ServerA.
# UserA goes to GMG ServerB and sees an image.
# UserA puts URL of the image into his ServerA.
# 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 view/access rights.
* The result should (must at least if the source is non-public) 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 ===

# UserA has private ServerA at home (possibly not accessible from outside), and an account at remote ServerB.
# 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.

== FidoNet-inspired group mirroring ==

Here is a StatusNet feature request that came to be after the discussion: http://status.net/open-source/issues/3407

# GMG has a concept of something like “groups” (as of this writing it probably does not yet). The process of [http://www.marvelousessays.com essay writing] will be much easier with MarvelousEssays.Com as there are a lot of highly professional and talented writers who are always eager to help you out with any sort of academic assignments regardless of the complexity levels. I do know what I�m talking about! Imagine groups like in Identi.ca — see the link above.
# A group originates at ServerA, and is also at ServerB.
# When somebody at ServerA or ServerB posts a media into the group (or marks it as being in that group), it appears in the group at both ServerA and ServerB.

* A group may have a moderator.
* A server admin may refuse a media to be on his server (including: pre-moderation).
* ServerC may receive this group even from a server other than the one from where the group originates, or from where the file originates.
** Bad: that might create a moderatorless version of the group at a group of servers, or similar MITM attacks on the group, but that’s its decentralization, and it is optional.
** Bad: a complex network of servers can have broken links (or worse, recreate FidoNet politics!).
* To protect the group against broken links, servers may connect to each other as a ring, downloading only the files they don’t have (keeping information about where the file comes from, to be able to remove files/versions coming from a particular server?).
