I think that the out of space issues are not that different from any file system 
on write enabled snapshots - it certainly can be mysterious and confuse users, 
but that is something that we have to deal with in order to get this kind of 
sophistication into end users hands (documentation? better tooling like the 
snapper tool, etc?).

One of the harder challenges I think for btrfs is still getting the repair tools 
rock solid - how is our track record these days with repairing btrfs after bad 
things happen :) ?
