Comment 6 for bug 2000871

Yes, I think that is very much possible. But it also doesn't mean that we should not try to find a way in which qpdfview works in this scenario. For example, we also carry code so that it works on AmigaOS and OS/2 which could probably be considered equally or even more exotic.
