If I ran a Tor Hidden Service on a server, would it be possible to mirror it on one or more other servers, and use the same onion-address for all? I was thinking having the mirror(s) periodically checking the main server, and then start-up it's own Tor-service and http-daemon if it couldn't connect to the main-server for several tries.
What I'm really asking, is if it's possible to have several servers reveiling hidden services with exactly the same onion-address?
If it's possible, what would I have to copy from the main-server to the mirrors? Some config-file for Tor? The main-servers host-keys?
