I don't have something special to show but still ...
My first attempts with Zay-ES and Networking:
There is a physics system running on the server. The server also sends updates to all client 10 times a second. In order to get fluent movements I have another system on client side which interpolates between positions and rotations for entities which are currently moving.
I feel like I have to say thanks to (especially) @pspeed, @Ali_RS and @Darkchaos who helped me a lot getting into the world of EntityComponentSystems which are quite nice I have to say, I wish I had discovered them earlier but you know... it's never to late.
