And the overall message is that only the (prefix holder|originating 
ASn[s]) can tell you if it is intended or not.  Sadly, this is not a 
useful metric for a third-party to use to determine prefix annoucnement 
legitimacy.  Perhaps an update to RPSL to allow for intentional multiple 
origins is overdue?
