The ability to set flags when doing some real time testing would be useful. i.e. I used pp in don't some testing on a customers WAN for a VoIP application. Being able to set something like numbered flags in the timeline would be useful for indicating when specific tests had begun and ended.

Also, how about the potential for a companion program to test one way latency. While round trip is useful, things like VoIP are really only interested in one way for Quality of Service #'s
