We have actually found Joe's documents to be very useful over the years, 
especially the ISC tech notes and RFC 4786.  E.g., the articles pointed 
me toward the use of clonable loopback interfaces in FreeBSD, which made 
the signalling of service availability much easier than using lo0 for 
loopback and service addresses.  The ;login article is new to me; I look 
forward to reading it.  Thanks.
