Yes (for a larger value of "all" than RealPlayer

run under Windows. I think that MacOS is the only orphan in this

gateway to something MacOS can handle (assuming they can't directly
view H.261 multicast with some other tools).
Recent QuickTime versions can receive IETF multicasts just fine.
I don't know whether they provide RTCP feedback though.
