It would have been bitterly ironic if the all-but-unannounced P2P 
pseudo-multicast traffic had interfered with the one high-grade multicast 
feed that was available to us. 

We saw unicast traffic peaks at almost 1.2 Gbps on our egress connections, 
with several campuses maxing out their connections, all attributable to 
Octoshape (since NYSERNet doesn't provide transit to any commercial streaming 
sources). I'm glad that the network was used, but I do wish that they could 
come up with something a bit smarter.
