Yes (for a larger value of "all" than RealPlayer supports). vic/vat/rat
are portable to many UNIX variants, and also run under Windows. I
think that MacOS is the only orphan in this scenario, but ISTR there
are protocol proxies available that will gateway to something MacOS
can handle (assuming they can't directly view H.261 multicast with
some other tools).


The Mac has the "SillySAPClient" which creates SDP file which Quicktime can
handle.

And the most excellent MacTV, U Oregon operate a content server.

They offer H.261 and mpeg1 support.

You can only view streamed mpeg1 with the Quicktime 5 public preview.

(Those folk experiencing problems with Multicast and MacOS 9.1 try upgrading
to Airport 1.3, it seems to fix the problem.)


There's even a multicast streaming server or two....

(Doesn't generate SAP Announcements but that's not a huge problem)
