As I understand it, if server 'A' is currently 'live', then as soon as a user updates a file on server 'A', you want to replicate that change to server 'B'. Similarly, if they are on 'B', you want changes replicated to 'A'. This replication should take place in real time, or if the 'other' server is not available, as soon as it becomes available.
