Dave:
 
I guess you would need to ASK the NAD at the other institution.
Was it done from a generic address like POSTMASTER or MAINT,
or from a real person's userid?  You did not ID the site so
I can't see if they are a bitnet node.  If they are, then
BITEARN NODES id's the NADs and other contacts.  LDBASEtte:
 
s * IN PEERS WHERE NODE bitnode
P CONTACT
