I've got an HP KVM at work. Supposedly like a $1500 unit new. It supports 8 machines...also works over a network, which is cool but I haven't played with that. Lots of other stuff I haven't figured out yet as well.

1999 Silver Frost SVT #609 of 2760 Quaife, lightened SVT Flywheel, SPEC stage II clutch, removed resonator, k&n drop in - various other goodies too.
