Per-file isn't available yet, tho at least per-subvolume is roadmapped, 
and now that we have the properties framework working via xattr for files 
as well, at least in theory, there is AFAIK no reason to limit it to per-
subvolume, as per-file should be about as easy once the code that 
currently limits it to per-filesystem is rewritten.

But actually fully working per-filesystem raid56 is enough for a lot of 
people, and actually working per-filesystem N-way-mirroring is what I'm 
after, since I already setup multiple filesystems in ordered to keep my 
data eggs from all being in the same filesystem basket.
