I feel it's time to start heavy lobbying for finishing FreeBSD's implementations of XFS and raiserfs :) (ZFS is not the ultimate solution: 1) replacing UFS monoculture with ZFS monoculture will sooner or later yield problems, and 2) sometimes a "dumb" unix filesystem is preferred to the "smart" ZFS).
