I have an old 4 system kvm switch that i haven't used for well over a decade. the alternative I use is to run the anon system in a Linux KVM (not to continue to be conflated, of course - lol). regardless of method, the rub is in operational security, assuming sufficient technical skills.
Lodaga: yeah, thorazine is on point. no offense, but i'm not watching that. i have limited, expensive bandwidth.
