[AG-TECH] Wireless Multicast in Access Grid?

Unfortunately many wireless hubs intentionally block multicast  
because of the potential to completely swamp the connection with  
mcast traffic.  We ran into similar issues with a robot that used  
802.11 to connect itself to the AG. The solution was to depend on a  
unicast bridge to connect into the AG and ensure that the AG traffic  
was isolated enough that it would not swamp the meager bandwidth of  
the wireless interface.
