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!)
