I am very interested in support for this functionality. I have been using mdadm for all of my redundant file systems, but it requires I have homogeneous partitions/drives for a volume. I would very much like to use a heterogeneous drive structure for a large redundant volume and have been waiting in anticipation for btrfs to come forth with this functionality.
