Lots of:
        - Cisco Load Balancer (or Alteon or F5 or ...), expensive
        - reverse Proxy in between Pix and servers
        - DNS RoundRobin (and checks on the DNS server)
        - Linux Virtual Server - with ICMP redirect
        - STONITH type of scripting on the IIS systems, taking over
          the IP address of the broken system
