All things related to multicast

The only problem with all of these things is that its not an end to end, 
with the exception of possibly NAM.  ( Not too familiar with that tool) 
Unfortunately our core is not cisco...  nor do our internal switches 
support any kind of netflow... (Nortel 8600's have a limited feature set) 

I think I may have to write something... just go around the edge and check 
the switches to see which groups they have joined sucessfully.  That 
should not be a bad start for the time being. 

Thanks

You are right, most things 'out there' are stale, and seem to be dated 
from the heyday when multicast was a brand new shiney protocol running via 

tunnels and over Suns....

We internally are using Cisco NAM's for our tiny fleet of 6500's to 
obtain a glance at traffic across the core, and Dave Plonka's flowscan 
tools to get a generalized view of multicast traffic totals.

I also have some home-brewed/adapted tools, such as an SDR viewer and MBGP 

route table monitor and doo-dads of a sort. [*]  They're a bit dated as I 
need to include mcast IPv6 and such....

Of course, it all boils down to exactly what you are looking for which 
would lead you to the right tool for the job.
