Exchanging RT and non-RT traffic over the same physical link is possible with RTnet (look at the rtnetproxy under "addons"). But, from the real-time point of view, this only makes sense if you can predict (and/or control) precisely the non-RT traffic so that the impact on the RT side while receiving that traffic can be taken into account for the RT system design. That's something RTnet can obviously not influence as it depends on the design of those third-party devices you want to attach.
