> From another device on the network, the "primary" PIX will never
disappear.  If the "primary" PIX fails, the secondary sets it's IP
Address and MAC address to what the "primary" PIX had.  When the
"primary" PIX comes back up, it sees the other one out there and takes
the "secondary" IP and MAC addresses.

For all other devices that have to talk to the PIX, just point them to
the "primary" PIX IP address and the failovers will be unnoticable.  In
a crude test when were setting ours up, we did a "ping -f" (flood/fast
ping) from a Linux box to a router on the other side of the PIX. 
During the failover, we only lost about 1/3 of a seconds worth of
pings!
