If you have an area of filesystem that is shared + writable to both
containers, they could create UNIX sockets in that filesystem, rather
than TCP sockets. Also they could create named FIFO pipes.

Another option would be to create a shared memory backed file in shmfs
or hugepagefs and expose it to both containers.
