MarsSeed [1] filed a deletion request for sacks [2]: Pakage is defunct - it was a FOSS videoconferencing stack for an Italian NGO fostering digital freedoms in the 2000's. But the organization seems defunct now, and its websites servers have been shut down since at least 2016. Package maintainer/developer @robertfoster tried to revive this Python 2 and Qt4 based software in 2019 by porting it to Python 3 and Qt5 in 2019, but ultimately abandoned that initiative. Current AUR package is still on Qt4 and Python 2. But after my prompt and OOD flag for this update, maintainer disowned this. So I infer that they agree with my observations above that this package is not worth the effort now that its backing NGO and backend services are gone.
