[AG-TECH] CURRENT multicast debugging tools?

[Jennifer Teig von Hoffman]

This is a badly under-documented area on the AGDP. Anybody who could 
research this topic and submit it to the AGDP would be doing a very 
valuable community service. The AGTP tutorial on multicast debugging is 
a good place for novices to get started, but we have nothing 
intermediate or advanced on the topic at all and sorely need it.

Related to this topic (but not covering the whole thing), some time ago, 
this was posted to AGDP:

I haven't been able to try these yet; perhaps somebody else out there has?
