we tried to respect the fact that people indicated that there might be a
scenario where the nas does not know the location of the end host. if
this is the case then the nas can only send its own location
information. if it can include the location information of the end host
(in case it is known) then the more precise info is sent. 

you seem to suggest that we add functionality to allow the radius server
to request what information (end host vs. nas) it would like to see. we
haven't yet heard this requirement and hence we haven't added it.
