This setting indicates the state of the "Always use unicast bridges  
instead of multicast" checkbox at the top of the Bridging panel of  
the VenueClient's Preferences window (after the Save button is  
pressed). Therefore "multicast = 0" would correspond to the checkbox  
being selected, while "multicast = 1" would correspond to the  
checkbox being _not_ selected.

I would be surprised if this setting would be implicated in random  
RAT hangs. There have been some instances of this setting being  
incorrectly set (e.g. to "False") which later prevents the file from  
being parsed successfully and so prevents the VenueClient itself from  
starting up. That doesn't seem to be the same problem that you're
