[routing-wg]IRR usage arguments

Hello!

 I have difficulty in convincing my US colleagues that there are still some
 autonomous systems in the world which pay any attention to the IRR and 
 sometimes use it for filtering.

 I also having some difficulty in convincing my collegaues to update the 
 aut-num export statement. They do believe that the folloing statent  

export: to AS-ANY announce ANY

 is just enough for all circumstances.
 
 I kindly ask you to point me to any examples of autonomous systems which still
 cross-check periodically import-export policy. I know of at least one such 
 AS, it is AS15645.

 I also ask for the references to the autonomous systems whose routing
 policy (strictly) require from its peers a real export policy in the IRR.

 Any other arguments to the IRR usage are welcome.
