Today, this is not possible (at least, not easily). The PIX failover cable is a serial cable with some high/low pins to 
determine primary/secondary and box "upness". 

        Couldn't someone build their own by just taking two computers
        (e.g: linux boxes or *bsd or whatever) and having them listen
        to the ports, then talk across the network and replicate the
        serial port state via IP? That's basically what the old
        "emulate a serial link over IP" computer games hacks use. I
        wonder if you could even use the same software! :)  Of course
        this begs the question of keeping those machines up and fault
        tolerant, but that's left as an exercise for the reader. :)
