I known Q4OS, but it is secure? I think if Trinity desktop is secure, why is not offer by default in distros like Debian, Fedora, OpenSuSE or in others BSDs like OpenBSD, who kept KDE3 alongside KDE4 in their repositories for a long time? Mate (from GNOME2) have in other distros, but Trinity not. There are logs from Q4OS' updates to see if it have more security updates than Debian (for the packages from Triniry desktop)? I have doubts that Trinity's Konqueror is safe.
I seriously do not hate Trinity, if I see that it is really secure I will join your call for someone to port it to FreeBSD because I would use it myself.
