    <p>Harry,</p>
    <p>That's a great discovery/suggestion for the LCTG meetings.</p>
    <p><u><i><b>One question (or suggestion for the Test Run)</b></i></u>:
      How does the Owl behave in an un-moderated environment, where two
      or more attendees attempt to speak while someone else is speaking?</p>
    <ul>
      <li>Does the device broadcast the superposition of all unmuted
        microphones?</li>
      <li>Does the "voice presence" in the main speaker's microphone
        suppress the input of the other microphones?</li>
    </ul>
    Cheers,
    <p>Tony Galaitsis</p>
