PS/2 is definitely the way to go:
For a mixed ADB/USB Mac/PC KVM network, just switch out the connector needed:
1) at the computer side of the cable
2) at the input side of for the peripherals

You'll still need a double peripherals setup without either the ADB->USB or USB->ADB conversion at some point.
I wonder if it'd be workable to use the extra wires for switching Audio as well? If noise would be an issue on either USB or ADB, just use the redundant connector for Audio on either type of Mac or PC?
