is this different from the seamless/unity modes that are available in vmware/virtualbox? i think they behave in the same way, they host guest windows which are painted by an rdp like thing (possibly just rdp) but behave like regular windows in the host operating system. i remember making use of it back in 2013 or so.
i think the vmware one even supports 3d hardware accelerated windows.
