I guess I was recommending that it A. happen in the future, or B. they 
design future hardware with the ability to programmatically redirect 
the stream in hardware to a new device on the fly.  I.e. the OS still 
sees the same disk as mounted and writeable [sort of an on-the-fly 
bastardization of RAID 1] but the controller knows what it's doing and 
the special software would hook into that for backup/restore/repair.
