At my previous job (large .edu), we spoke MSDP with Internet2 through our 
regional I2 connector, however we turned that MSDP session off probably 
two years ago, and I don't think that session moved any useful traffic for 
probably two years before that.  Multicast was used extensively within our 
network, but nothing outside for quite a while.

I agree with general sentiment that multicast across the larger Internet 
is dead.

Thank you
