Wow never realized that the latest version of ngrok isn't open source. Strange that you can just hide versions of your software, because you don't want it open-sourced
Does Pagekite have the same introspection capabilities as Ngrok? Otherwise it's unclear what else Pagekite overs beyond what you can accomplish with a few lines of nginx config, sshd config, and bash (instructions: https://gist.github.com/gdamjan/4586758).
