ZFS is not handling replication on remote servers very well currently, 
and they don't seem to care about this from the reactions i had on some 
forums. And i would not use ZFS for production system on FreeBSD now.

FFS snapshots are stable in production, and adding a reading function on 
snapshot structures will not change stability :-)
