Right; it *can't*, unless all machines on the network have a hard real 
time layer between the NICs and the protocol stacks. There are 
protocols that would work for running RT streaming together with 
normal network traffic, but there's no way around the fact that all 
nodes must be hard real time. (Well, except for building it into the 
hardware, perhaps...)

That's not a problem normally, as most NICs have hardware latencies in 
the microsecond range. All you need to implement hard QoS guarantees 
is an RTOS, RT safe drivers and a suitable protocol.
