No, it doesn't. I don't believe there are any plans to implement 
hierarchical storage in BTRFS, but perhaps one of the developers can 
confirm or deny that. As for how to do it - I don't have any ideas other 
than what I mentioned earlier (aufs to overlay file systems and cron 
jobs to rotate things in and out of cache).
