This might be possible now - it wasn't when the infrastructure was built 
and it still seems like a bad idea to throw 60Mb+ multicast feeds onto 
the same physical interface with anything else.

Sure, but after doing one right, clonezilla can give you a thousand just 
like it without caring how it got that way.  I agree it's ugly, but it 
also doesn't depend those underlying commands being repeatable or the OS 
that they ran on.
