Thanks for ideas Jon. Reading your post I understand that in general you see Pingdom and WPM cover different use-cases. WPM is great for internal web applications, maybe from different branches. Pingdom is strong is external public-faced applications. Do you see any touching points, where WPM and Pingdom can complement each other, where together they can provide new value?
What about ability to monitor your external sites from Amazon cloud? How do you see this comparing to Pingdom abilities?
