You can run ASA LAN failover over one (or configure them separately).  I remember
reading (or think I did) somewhere that it was preferable to run this failover link
through a switch as opposed to a crossover cable, but I can't cite a reference.

Old PIX used to have this serial-cable heartbeat and LAN-connection-state combination.

We're running ASAs active/active over a common failover link.
