Yeah you can! Particularly with the java.net APIs; you wrap your hostname in
an InetAddress object and then pass it to a socket without really needing to
know that it's been resolved to an IP address underneath. And issues with NAT
only arise if you are writing a server - and even then you don't need to
*understand* NAT; the knowledge that servers shouldn't be "behind firewalls"
is enough for most people. I am more concerned about server authors knowing
how to implement an authentication and authorisation system than about them
understanding NAT...

Hmmm... you need to know HTML to make Web stuff, but not HTTP; I know people
who are writing server-side scripts with no real understanding of HTTP. The
advanced ones know that <? header ("Location: http://www.foo.com/";) ?>
magically causes a redirect, but apart from that it 'just works' that the
browser's request gets to their script.
