Yup. The msb and qb bridges are dumb in that they forward down each unicast 
link the aggregation of all traffic from the other unicast links and the 
multicast link (and vice versa, but that will likely be much less traffic).

If you're doing this anyway, would it be possible to convince the firewall 
admins to just let multicast UDP pass thru? (I think Bill Nickless has some 
slides somewhere on the security implications of multicast)
