= VNC: shadow =

Developed in-house, `shadow` allows for simplified VNC Screensharing between Thinlinc sessions, flips and notebooks
in the imath network. It is preinstalled on Thinlinc, on imath flips and imath notebooks.

 * Start "Shadow Screenshare" from the applications menu, a system tray icon will appear. (Bottom right on Thinlinc, top right on laptops & flips.)

{{attachment:shadow_icon_screenshot.png}}

 * Left click on the icon and choose either 'View' or 'Share with', a text box will appear where you can enter an ID. Real world examples:
   * Click 'View', enter `crose` to shadow a colleague with that username. They get a popup asking for permission.
   * Click 'share', enter 'enured' to share your screen with a colleague with that username. They'll get a popup asking if they want to see your screen. If they accept, it'll ''again'' ask you if you actually want to share your screen with them.
   * Click 'Share', enter a room number like `k11` or `k30` to ''project'' your screen to a flip nuc. These are configured to accept shares by default, so you'll get a view request right back.
 * A list of all your recent actions is kept, so you don't have to type your colleagues name each time. Simply select an action from the tray icon's menu.
 * To disconnect all connected clients, there's a button above the `Quit` menu in the tray icon's menu.

There is currently no clipboard or scaling support. It's planned for version 2.
