What Shared-X is popularly reserved for the systems that allow a single X client to be displayed on multiple X servers simultaneously. The MIT X11R4 server already has a `shared memory' extension that allows a program to create pixmaps that are shared between the client and the application. The application can write into the pixmap array directly, then tell the server to do a CopyArea from it, resulting in a very fast operation. We've used it to good effect here already.
