Yep.  And as with DNSSEC, you, as a network operator, get a choice.   
You can configure a single trust anchor corresponding to the actual  
address allocation flow and follow a chain of authority down to the  
leaf (end user or ISP) allocation or you can configure a number of  
trust anchors and figure out how to deal with cross-certifications  
resulting from the multiple roots.  Ignoring politics, the technically  
and architecturally cleaner approach is obvious to me.  However, as I  
mentioned, it is challenging to ignore the layer 9 politics.
