The problem I see with this is that the two RasPi's would have to have
very similar file system structures, running the same services, with the
same codes (RFID and keypad).  We could set this up initially, but I
think it's very likely with the way things are hacked at hacker spaces
that the two will get out of sync, which means we'd have to periodically
clone one SD card from the other.  I think it would be kinda tricky.
