sockets, memory mapped files and sysV shmem

Requirement -- Large volume data sharing across jvm and other unix processes.
1) DB is the most common solution.
2) sockets are well supported in java, c, perl, python but still requires copying lots of data
3) memory mapped files as a RandomAccessFile and MappedByteBuffer? Pure java solution -- No JNI needed. I feel not so "popular". May work in specific contexts.
4) sysV shmem? Presumably faster than data copying solutions like pipes, message queues, file-based. But JNI needed.
