The traditional IP KVM is the second thing Lionel described. The idea
is that you can have any mixture of RS-232, VGA + PS/2, DVI + USB, etc
on a single KVM unit, all dongle traffic running over either cat5 or
proprietary cabling. All of this has a single web interface.
They tend to be very expensive, and I've never used one that was worth a
damn. (e.g. the RS-232/vt100 function is often a complete VGA terminal
emulator, presented via the same java applet as the regular KVM hosts!)
