I'm certainly no expert...but I've tried getting it to work on my modem
(supposedly the University is on the MBONE for multicasting)...but nothing
worked. From what little I know, not only do the end points have to
support it, but all the routers in between as well. I've tried some of
the multicasting tools on campus (NV, VAT, SD/SDR, etc)) and haven't had
much success. I don't know too much about it either though...just that it
generally doesn't work over large distances on the Internet (especially
modem to modem as the end points). Of course, IP tunnelling could come
into play... I've heard it works great on internal lans which support it.
