title: Simplest way to publish over Zeroconf/Bonjour?
body: <p>I've got some apps I would like to make visible with zeroconf.</p>
  
  <ol>
  <li>Is there an easy scriptable way to do this?</li>
  <li>Is there anything that needs to be done by my network admin to enable this?</li>
  </ol>
  
  <p>Python or sh would be preferrable.  OS-specific suggestions welcome for Linux and OS X.</p>
