The Xocean node can be used as a deformer (by using a non-simulated ICETree on geometry objects) or for creating interesting particle simulations. The node outputs the displacement values as well as the eigenvectors and eigenvalues for each point in world space.
The advantage using an ICE Node is that the outputs can be combined and reused in the ICE Tree (e.g. colorize foam or emitting particles where foam occures)

The node outputs the displacement vectors as well as the eigenvalues and eigenvectors per point.
Here are some pictures of Xocean in action:
