Abstract
Apparatus, systems, and methods may operate to send a window copy message including changed window identification information to a remote node when metadata associated with a changed foreground window at a local node has been cached, and otherwise, to locally cache the window metadata and send the window metadata and window pixel data to the remote node. When a preselected minimum bandwidth connection is not available between the local node and the remote node, additional operations may include sending a rectangle paint message including changed rectangle identification information to the remote node when rectangle metadata associated with a changed rectangle of a designated minimum size at the local node has been cached, and otherwise, to locally cache the rectangle metadata and send the rectangle metadata and rectangle pixel data to the remote node. Additional apparatus, systems, and methods are disclosed.
