Yes, I agree on that. However, psychologically pulling AC power cord (or executing shutdown command) is more grave action than pressing toggle "on/off" switch image for network interface, thus killing network connection. So, I both agree and disagree with you. Namely, as with power I agree that local user (especially armed with screwdriver) can do a lot. Yet, I disagree that centrally managed "UNIX - like" (allegedly) workstation can be easily subverted in variety of ways by local user, effectively obliterating what sysadmin configured with something specific in his mind. My apologies, everybody. If I held myself from putting my rant when I asked for help, there wouldn't be any abstract discussion on topic none of us can affect...
