I cannot guaranteed how GSX will work in wideview but from a licence point of view, you have 6 activation with an order so, if you are VERY careful and remember to ALWAYS Deactivate BEFORE making an hardware change, you might get away with running 5 PCs with 1 license. We are not opposing that, as long as you are the only user.
However, if 6 activations are not enough, we have a Volume Purchase discount, that is specifically directed at Home cockpit builders running many networked PCs, that allows you more activations.
