The ``npemwin virtual appliance'' (npemwinVA) is the name of a package for running npemwin in a VirtualBox VM. It used to be a separate package but we now include it in the nbspVA package so that the user can enable Nbsp or Npemwin at will in the same VM.
It is a specially configured installation of Ubuntu, together with all the packages required to run npemwin, already installed and configured. The entire npemwinVA package can run in a Windows computer as another program, with exactly the same features of the npemwin package that runs in a FreeBSD or Linux computer. Other applications such as MetarWeather and Digital Atmosphere, running on the same or a different computer, can connect to npemwin in exactly the same way as explained elsewhere in the Npemwin manual. These screenshots illustrate the setup.
