Wow that looks great! The URL has an extra "dot" before the SHTML though when you click on it.
Easy fix though. Are there no commercial applications for this kind of monitoring?

I see your graphs are powered by MRTG. =)

Interesting question, I'd like to know more about this myself. I'm so used to monitoring SNMP-based

devices, never really thought about multi-casts and being able to see the pattern/tree....



Shameless plug, I once developed a tool which was called multicast weathermap. You can see what remains of it here:
http://netmon.grnet.gr/multicast-map.shtml

(hover over the nodes and the links and you can see various useful info)(you can see the tree of a specific group by 
selecting from the drop down list at the bottom)

and the presentation here
http://tnc2004.terena.org/programme/presentations/show2c2c.html?pres_id=47

Since I too myself am into multicast, I intended to incorporate into it everything needed to know everything. But 
eventually it was left as it is. 
Apart from that, the NNM advanced used to have a multicast plugin, and it was fairly usable. You could take a look at 
it probably, but I don't know whether it can handle those MPLS cases you mention. 

Lastly, those guys at Poznan used to work on a tool called Muvi http://muvi.man.poznan.pl/You may want to take a look, 
although I fear it too has been abandoned.
