The knowledge that route (a) was originated by AS (x) is only meaningful insofar as one has some set of high-confidence beliefs/expectations about AS (x). However, if AS (x) can change hands at will, henceforth no such confidence will be possible for the overwhelming majority if not all ASes.

I think that is what was said. However, I'm not sure Owen or Tom 
classify themselves as RPKI experts, please correct me if I'm wrong. 
And, if I'm wrong, I apologize.  Further, this is the first I heard of 
this being an issue, it's never been brought up in any of the several 
RKPI talks I've been to.

I would appreciate comments from RPKI experts on this issue.  If ASN 
transfers actually create additional risk within RPKI, then that is 
something we need to consider.  But I for one would like to have a much 
more detail description of the problem and/or a pointer to previous 
discussion of the issue.
