In order to have multiple applications from the same VM be opened at once, we can use multiple monitors in the guest and multiple spice sessions in order to display multiple applications. The monitor can be specified in the guest using a script found on StackOverflow. winmin-viewer-multimonitor.c starts implementing multimonitor support, however, I need to use dbus to communicate the current monitor from running instances of the viewer. For example, if a opens Word, then opens Excel, closes Word, and then opens Word again, the application must be able to reassign Word to the original monitor that is no longer being used.

To make it possible to use applications like Garmin Express can there be an option to allow USB passthrough if an application requires it.
