This here is a good example of the OPPOSITE of what I need:
Newegg.com - Rosewill RKV-2DVI KVM
It is designed for users that have a keyboard and mouse for each computer already plugged in but just want to use 1 monitor.
It does however have one really nice feature - the extended button switch, which I could use with my foot like a pedal - that is awesome (some of these things come with software that switches, which I'm guessing would be really effin annoying).
The only thing I have against VGA is that the cables I have from TRENDnet give off a really blurry video output. Sure I could get better ones, but meh, still need a KVM that outputs multiple USB's from a single source (not the other way around).
