A South Korean company has developed an app that sets up multicast on a network automatically.  No router config required.  It does it with a small active-x that installs on a user's machine and gives a server on the ntwk all the info it needs to route the multicast stream.  Pretty cool stuff.  I'd call it a killer-ap for multicasting.
