I've never tried the following setup myself, but you should look into the possibility of using geom ggated/ggatec and gmirror in combination. Basically ggated/ggatec will export the raw block device over the net, so that another computer may use it in a geom stack. You could have the second computer export it's disk device, and let the first one use it in a mirror (raid) setup. Since ggated on the the second computer would claim the device, I think you could only mount it read-only, but it would be synced live, I think. Note that I don't know these tools from experience, only from what I've picked up here and there. You would have to read up the specifics yoursel= f.
