It does support storing multiple urls, and will try each until one
works. I just don't have much of an interface for adding/removing the urls.

If you're using a backend like SHA1, then if you simply run addurl on
both urls, and they have the same content, you'll get two annexed files
that share a key (and can then delete on of the files). git-annex does
record that both urls can be used to obtain the key. So that's one way.

Or, you can check out the git-annex branch and look in remote/web/ for the
files that contain the urls, as documented at

No interface currently, but see above.
