  <blockquote>
    <p><strong>What are the minimum hardware requirements for the BigBlueButton
    Server</strong> As a minimum, we recommend you run BigBlueButton on a dedicated
    quad-core machine with at least 4 GB of memory and a 2.6+ Ghz
    processor.</p>
    
    <p>We recommend installing BigBlueButton on Ubuntu 10.04 32-bit/64-bit on
    the server (see Installing BigBlueButton).</p>
    
    <p>While the BigBlueButton VM is a good way to try out the system, we
    recommend you run BigBlueButton on a dedicated server to reduce audio
    lag. In a virtual environment, the BigBlueButton VM gets only a
    portion of the host's CPU, and any lag in the CPU cycles can translate
    to lag in processing VoIP packets.</p>
    
    <p><strong>What are the minimum bandwidth requirements for the BigBlueButton
    Server</strong> You'll need good upstream and downstream bandwidth from the
    server. We recommend (at least) 100 MBits/second bandwidth in both
    directions.</p>
  </blockquote>
  
  <p>Personally, I'd probably looking into a SaaS solution like Webex, GoToMeeting, or the like.  There are probably at least a half dozen solid options.  Without having done it before, I'd hate to have sole responsibility for a conference that big.</p>

Comments.Text: Do all the users have to be able to send video or just the presenters?  Whatever you use would have to be able to select a user to present at any given time and have the video feed only sent on request or the data rates involved would become completely impossible to sustain.  You probably want to look more into remote presentation software than video conferencing software since video conferencing tends to be more of an everyone sees everyone kind of thing.
