Very cool.

ngrok doesn't have a programmatic API, but I'd love to add one soon. I've built out a library for this in https://github.com/inconshreveable/go-tunnel that will be the foundation for ngrok's next version providing a library in addition to the CLI tool.

Unfortunately, one of Go's weaknesses is that it doesn't embed into other languages like C, so I'd need a ground-up rewrite (in C, probably) with bindings to other languages.

If ngrok the command-line tool had a well defined programmatic interface (like RESTful JSON) would that useful, or is the burden of a separate binary/process to manage still too painful?
