Why Putting SSH On Another Port is a Good Idea
  2. Next he talks about this non-root listener issue. He 
  claims that you shouldn’t run your SSH daemon on a 
  non-privileged port because anyone can spin up a daemon 
  up there. Great point, except you can still do that even 
  if you run your main one on 22.

I don't think I understand this point at all.  What is it that you're trying to say?Are you sure you understood the original post's point?  djc@capelis.dj:~$ nc -l -p 14
  nc: bind to source :: 14 failed: Permission denied
  nc: bind to source 0.0.0.0 14 failed: Permission denied
  nc: failed to bind to any local addr/port
  djc@capelis.dj:~$ nc -l -p 1414
  ^C

See the difference?(Edit: The original blog entry has now been edited to slightly clarify the wording.  But the update mostly seems like an attempt to rapidly justify the author's original point.)
