    Clients and servers MUST treat DUIDs as opaque values and MUST only
    compare DUIDs for equality.  Clients and servers MUST NOT in any
    other way interpret DUIDs.  Clients and servers MUST NOT restrict
    DUIDs to the types defined in this document, as additional DUID types
    may be defined in the future.


That section pretty much ends any further discussion on predictability, as i am not permitted to make use of that.
