    My problem with this the last time was that it did ndbipinfo
    itself, which is always going to cause problems.  What if cs 
    is running on a different machine and you don't even have
    access to the network databases it is using?  I realize this
    is uncommon but Dave did work hard to make remote network
    stacks work.
    
    It turns out that /net/cs already does what you want,
    almost.  It has a magic query
    
    	!ipinfo sys=you smtp
    
    which will return
    
    	smtp=your.smtp.server
    
    The only problem is what to say as sys=you.  Really you
    want the IP address that cs is using.  So I changed cs
    to use ip=its.ip.address when you omit the attr=val.
    So now
    
    	!ipinfo smtp
    
    will return
    
    	smtp=your.smtp.server
    
    which is what you're looking for.  You'll need to look
    at the network address being dialed for any net prefixes.
    That is, if the address being dialed is /net.alt/tcp!$auth!smtp
    then you need to ask /net.alt/cs not /net/cs.
    
    If you change the patch to use this mechanism to figure out
    how to translate $smtp then I'll gladly apply it.
