Its good to see the message in that venue worked. Its intent is to  
warn people of exactly the situation that you describe.

What follows from that is that, if you want a really secure meeting,  
you need to be able to restrict entry to the venue so that unwanted  
participants can't gain access to the  streams' encryption keys. The  
AG toolkit provides that functionality through the use of  
certificates. Any venue _can_ be set up (they're generally not) to  
allow entry only to participants with the correct identity certificate.
