Yup we'll still have some patience to go apparently.

(And regarding my hopes of btrfs, means I'll have to learn to compile my own kernel and compile a 3.10 kernel with modules and btrfs enabled. )

(Or try to find a fuse btrfs driver. Well given that btrfs is not only a filesystem but a whole volume manager, and that it actually uses in-kernel facilities (device mapper for the volume management, crypto for compression, etc.), any existing working btrfs fuse solution probably roughly looks like recompiling the whole kernel)
