I pretty well finished the technology part, if I recall. I remember working on automating it so that all the shader tweaking that had to be done based on the y-coordinate of the water surface would be handled without user intervention. Prior to that, when you moved the water surface prop up or down, or you moved the camera, you had to go into several places in shaders and update some numbers. 

I'm pretty sure that all that remains is to document it and package it up.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
