I took the plunge and bought a Zonet KVM 3004 4 port. What a treat! Running it with a dell 19 inch crt @ 1152 x 864 x 75 mhz on a lowly Geforce 440 maddog dual head, in single head mode on an Acorp 815 chipset dual P3 as the main monitor, and as the secondary on a slightly better Geforce 5200fx maddog dual head on a Asus A7N8X-E with a microsoft optical mouse and house brand keyboard; I have to say this thing kicks major ass. It's pure plug and play sex. It powers over the connections, though you can use a wall wart if you don't already have enough of those. Double hit the Numlock, and choose 1-4 for your computers connected to it. You can boot them all at once and they think they have a monitor, mouse and keyboard connected. Sweet. I can already see that it may be best to use a mouse for both machines, but sharing the 2nd monitor from the 1st machine and the keyboard seems fine. Too many monitors in the bridge area are not a good thing, and the desk is always full of %^&* already, let alone multiple computer keys. One of my concerns was that I was already using long cable extensions for the mouse, keyboard and monitors, but the additional cable seems to be no problem at all. The 4 sets of KVM cables that come with it are bitchin' quality and would probably cost more than the $48.00 US I paid for the whole shootin' match, plus tax, huntin' license, gas and alcohol consumed during the hunt 
This may just make fxteleport happen, if I can get the demo to work over firewire lan....my 100 and 1 gig lan connections are busy lanning for lemmings...I'd like to try midi over lan to other boxes and other things. This puppy earns the *Git Woneadese* award of the year. Smooth switches, and great video through it. If nothing else, I'll have a kick ass duallie surf box It even cuts through the fog and beeps your ass when you switch.mrc
