No, I didn't forget it.

Dynamic DNS can be, yes.  It depends upon the way the zone file is 
updated and whether it's Internet-exposed on not.

If we're relying on mDNS we're probably disconnected.

But you've been around long enough to know that security and convenience 
are inversely proportional.

RFC 2782.  Becoming more common, and very common for VoIP networks using 
SIP.

Why yes, yes I did push the management elsewhere.  If you have a hundred 
thousand cloud nodes, where would you rather manage them; at the 
individual node level, or in a centralized manner?  Go to a cloud panel, 
select 'deploy development PostgreSQL server' and a bit later connect to 
it and get to work.  (Yes, I know you need AAA and all kinds of other 
things, but for the application developer who needs a clean sandbox to 
test something, being able to roll a clean temp server out without admin 
intervention could be very useful).

Embedded devices, with what I would consider to be full Linux 
distributions on them, with nothing more than a network device to manage 
them already exist.  Network device meaning Wi Fi, too.  NAS appliances 
are but one application; the WD MyBook Live, for instance, has a 
complete non-GUI Debian on it, and there are repos for various packages 
(for grins and giggles I installed IRAF on one, and ran it with ssh X 
forwarding to my laptop).  Is a NAS appliance not a server?
