In general, Ethernet is the medium over which your relevant data is carried (there is a protocol for this that includes frames). You write a protocol that is carried over Ethernet and use that to communicate your data.
IP is a natural way to do this since most applications support this natively (it is the default in most cases). There is nothing preventing you from assigning IP addresses to these two machines and using teh VNC software over that. The most you may have to do is set up routing rules and assign a static IP address - neither of these things is terribly difficult.
