BTW it's a valid use case to safely place one of the mirrors far

I thought those things used something else than raid...

Running RAID on top of a SAN (iscsi) device is certainly possible.
Almost certainly also on top of DRBD devices.

I meant one element local disk, another over the network.

Yep the rich people would use a really fast network for this and the
poor people would use write-behind and write-mostly :)
