Do you mean using raw ethernet packets on a flat bridged network to do
point to point IPCs in a cluster application?  No TCP/IP?

Sounds like a lovely project.  Why don't you report to the list once a
month or so.  Just remember, while you can likely skip the IP part
(which is primarily associated with name resolution and routing) and can
maybe skip the port part (dedicated function packets) you'll still have
the rest of TCP to recreate -- reliable packet transmission and
sequencing and checksumming.  Pretty ambitious, if you're planning to
write the whole communications stack yourself (but yes, a great learning
