Well, if the filesystem in filesystem/diskA and filesystem/diskB is the 
same (multi-device) filesystem, as the above definitely implies...  Tho 
based on the context I don't believe that's what you actually meant.

Meanwhile, send/receive is intensely focused in bug-finding/fixing mode 
ATM.  The basic concept is there, but to this point it has definitely 
been more development/testing-reliability (as befitted btrfs overall 
state, with the eat-your-babies kconfig option warning only recently 
toned down to what I'd call semi-stable) than enterprise-reliability.  
Hopefully by the time they're done with all this bug-stomping it'll be 
rather closer to the latter.
