Rage,

I thought of that, but I don't have fluids at work. However, My next thought was just to make a plane, give it a lattice, make some clusters, and animate it deforming. The thing is, my particles don't seem to care about the deformation. I've tried making my plane a surface emitter, and a directional emitter, but neither of them work. The particles ignore the plane's deformations once emitted. I've tried tweaking the weight, conserve, inherit, and emmision in world settings, but to no avail.

How do you make them "ride the waves"?

Thanks.
