Yes I was referring to SA query capability, such as a path record query.  Since 
the spec requires that the path information be provided by the active side, I 
think that such a device could work without change.  (But it does mean that the 
active side has to provide some way to obtain the necessary information to put 
into a CM REQ, plus know what the remote router will do.)
