I am the newbie that benefited from the discussion.  As you can tell, I have 
a head full of telephone cr*p that doesn't matter anymore.  IT and VoIP is 
all that matters now.  In the future when you use the telephone analogy say 
that telephone number translation is like DNS rather than DNS is like DN 
xlation - that way you imply which is the dominant technology :-).  DNS and 
LDAP will be the xlation technologies to know going forward.  Luckily, IP 
numbers are already portable and there no monopoly control of them so there 
is no need for band-aid technology to remedy that situation.

The larger purpose of the economic order, including Wall Street, is to 
support the material conditions for human existence, not to undermine and 
destabilize them.
