We have been doing a lot of work on how to measure the subscriber "experience" of a network. e2e ping delay actually is quite a good measure so long as you use it correctly. However we found that using tools such as iperf to take periodic measurments of TCP throughput, UDP throughput and packet loss was far more interesting.

You might also find this OWAMP (One Way Active Measurement Protocol) AKA "One Way Ping" implementation to be quite useful for that sort of thing. http://e2epi.internet2.edu/owamp/ -- "Sheep are slow and tasty, and therefore must remain constantly alert." - Bruce Schneier, "Beyond Fear"
