Xroad.js
Xroad.js will soon be a command line tool and Node.js library that implements the Estonian X-Road protocol and provides a way for you to send requests both from the command line and programmatically from Node.js. It doesn't nearly do everything the "official" [security server][security-server] does, but it sure does its subset quicker and with far lower resource requirements. The former is hundreds of megs of Java and Ruby, after all.
