We're currently using the xattr interface for DOS attributes, and soon for NT ACL support, but it doesn't really fit as a streams interface (no lseek() support) although someone in HP coded up a test interface to NT streams that map into xattrs (most of the streams in a Word file for instance are quite small) - but I really don't want to have to do this :-).
