Well I *think* that's exactly what I described. One for the public traffic and one for the interconnect. So the answer must be 'yes', and indeed 'this is bog-standard typical RAC'.

Yup, physically. When you install RAC you are effectively installing an Oracle component which sits atop whichever NIC you specify should handle the interconnect traffic, and acts as a message-passing conduit for instance-specific traffic. That is, Linux must have a Cluster Management Services component, and Oracle's own CMS bits and pieces interface with that to handle the inter-instance traffic.
