Egads. All this hate for apple extended attributes. Reliability for AE is really only a consideration in special cases like BTsync or with admins who are too lazy to properly handle the macs using services on their network. Also; anyone who has used a project management system that integrates with apple labels for automatic status updating, or reads out status via labels would be sympathetic to their usefulness. It is fantastic. I am totally unsurprised by btsync not handling AE given the way it works. It would be nice in the future, but *shrug* I have this feeling that coming up with a sensible way to sync ae is going to be a pain.
