Those are both very simple reports to run from PCH's existing databases 
and data-feeds.  The only tricky part is how you specify the organization 
name...  Are you planning on using the RIR OrgID, or an exact-match on the 
organization name, or a substring or regex match?  Or would you like 
something that tries to map through origin AS?
