All sorts of cool options. :) I'd expect mmap(2) and sysv shm to be the most portable when you want to share a lot of memory, and unix domain sockets or tcp/ip sockets to be most useful when you want to share a stream of bytes, rather than shared random-access modification of bytes.. W. Richard Stevens has written a book dedicated to interprocess communication under Unix systems. Recommended reading, as is everything he wrote.
