Yeah most operating systems have single user mode.  If you can remotely boot
my mac and hold Command-S, I'll start worrying about that one.

Find any linux box and boot with S on the kernel option line.

Solaris can have this done too.

By the way if you're that close to a mac why not boot it in target disk mode
and just read all the data off the disk with a firewire cable?

Physical access == no security pretty much.
