A/UX got about as close to being a full System V implementation as you can get without being one. As for inter- process communications, you get all of System V IPC (semaphores, shared memory...), but you also get Berkeley 4.2 sockets. -- Gerald Permission is granted to make and distribute verbatim or modified copies of this opinion, as long as this permission notice is preserved.
