There are other things that can impact application traffic behavior beyond
a dropped packet.
Off the top of my head:
1. Out of order packets from load balanced connections
2. Layer 7 Content Manipulation
3. Higher average latency of one stateful connection over another.  IE one
transaction can get "ahead" at the cost of another, altering all traffic
behavior after that point. This is similar to #1.

Good point Chuck, it seems that we only have
nominal control over #3 in a test set-up.
Worth discussing the implications on input stream
repeatability a bit, hopefully today...
