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.
