I was thinking of doing more distributed mirroring, I want one mail server in one end of the country and another in the other end of the country and they should be synced. I could setup two iSCSI devices (SCSI over IP), one on each machine, and then run software RAID-1 on them from the two places. I wonder if there is a free or open source file system that could handle concurrent access? This would actually be a much more clean approach than using rsync, which I've also been thinking about.
