Hi all, I have written a rough design on how to implement per-surface remoting on Weston, primarily over network: https://people.collabora.com/~pq/Adit/Weston-IVI-remoting.pdf
Before you get carried away, I must note that this will not work on desktops without considerable work. The design is written for ivi-shell which has a trivial Wayland protocol extension. The design could support desktops too, in theory, but you will need to think how to get all the desktop shell protocol features implemented, and you probably want something friendly to control the remoting, too. What this design does do, is give a plan how to remote the essentials of the core Wayland protocol. This includes creating wl_surfaces and wl_buffers, transmitting pixel data, feedback in the form of frame callbacks, and also relaying input events, and how to expose remote output and input to Wayland applications. The document is not a rigorous technical description, but a high-level plan on what we will likely be working on in the following months. You have already seen a few patches or RFCs originating from this work. Serious feedback is warmly welcome, but please keep in mind that this work is not aiming for the desktop as is. I would love to hear if you have plans for or have implemented something around the idea of remoting individual Wayland surfaces. Collabora is working on this by the request of ADIT. ADIT is joint venture company of DENSO Corporation and Bosch GmbH. Thanks, pq
