The 2.6 Linux kernel includes the ability to create this sort of havoc on your network interfaces via netem[1]. Using the `tc` tool you can add latency, jitter, packet loss, packet reordering, corruption, duplication, or rate limiting. You can apply this to an entire interface or have it only apply to single IPs or ranges of IPs as it works through the existing QOS framework in Linux. Combined with a routing interface and you can leverage this to create a wan emulator for external hosts without much trouble. This is incredibly useful when smoke testing large scale distributed systems or for test/development of protocols intended to be used over dicey connections.
