See also Aeron[1] which is basically a networked superset of the Disruptor, featuring (IIRC) a just-as-fast machine-local implementation. Made by some of the same people as the LMAX Disruptor. It's not quite ready for general use AFAICT, but it's quickly getting there...
There's also a really informative presentation[2] by Martin Thompson on some of the ideas that they're using to get really low latency and high throughput.
