- What I'm missing is any kind of encryption support.
  It would be nice to include encryption support into btrfs (as long as the on-disk file fromat isn't finished),
  so one can easily handle (upcoming) multiple device (raidB/B2) targets with one key.
  For now I would have to setup LUKS below btrfs, which is very suboptimal for multiple device configurations (raid)

°raidB/B2 is a synonym for btrfs enhanced raid5/6 ;)
