This seems frighteningly sane. Again, I applaud your sense of design.

This bothers me slightly. Perhaps the register command could have an 
optional flag to force this entry to the top of the list (and it could 
work even if the archive is already registered. If you have 5 mirrors, 
and want to set one to the top, it would be a bit of a pain to have to 
unregister and reregister 4 of the 5.

It's a corner case, so it's not critical to have this feature, but it 
would be a nice touch, and I don't think it adds much complexity.

Long, but scriptable (and abbreviatable as you point out). Any chance of 
supporting:
  arx mirror address@hidden --updateall

to automatically mirror the master to all the listed mirrors? I 
personally can't think of a use for updating one mirror but not the others.

Will/does ArX check to ensure that only one of the listed archives is a 
non-mirror? Are there any checks you can/will do to help users avoid 
ending up listing unrelated archives as if they were mirrors of each other?

Thanks,
