* Make MS Windows framebuffer and input frontends available so that Linpicker can be used with
  Windows guests.  Also provide track support for Windows so the combined desktop can be used.

* Move Linpicker to a model in which linpicker-monitor handles all privileged Xen operations,
  including mapping guest framebuffers and sending input events, while linpicker-server acts as
  a normal user application and requires no privilege.  This will require a client/server model
  probably using a local socket, with shared memory used to share the framebuffer.

* Move away from DirectFB and legacy /dev/fb0.  Instead use the modern graphics stack including
  DRI, GL, and KMS to implement linpicker-server.

* Add desktop features to Linpicker including a clipboard, unified start menu (application
  launcher), and notification messages.

* Integrate concepts from XenClient such as graphics passthrough or USB input device emulation.
