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

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.
