Hi guys! I’m still alive!!
Regarding 'question… as I said I don’t know at the moment if the shader will be available for all of you, mostly because it will be used in a commercial game we are developing, so we have a lot of things to consider.
But I also said that I’ll do some sort of guide or tutorials, sharing what I’ve learned doing material. 
At the moment I’m still making changes… I completely redone (for the 3rd time!) the wave generation node… I’ve read a lot of papers and book pages about oceanography… the hardest part was try to choos all the values in order to have something that looks real in its behaviour. There are precise reletionship between all the parameters in a sea, and I deeply wanted to find all these relationship and put them in the shader.
Now the waves are better in my opinion, and also the surface look: I’m still struggleing with the “stormy” sea, that seems to need a lot of fine tuning to have a good look… Calm sea is quite easy to achieve, but big waves and storm easily breaks the magic! 
I’ll keep you updated in the next days with some images/videos of new (and I hope last!) version
