There so many moving parts that this could either be a great tool to analyze data or it could open up a can of worms which could lead down the road to network re-architecture. If this takes into account best effort or SLA based ISP, Network topology, QoS, Packet Prioritization, etc then I think it could be a useful tool. Without it it's just a tool that spits out pretty pictures. If your main selling point is data then it has to be more than just what latency can show.
