How can I call a C++ cgi from Meteor server?

I love meteor, but my background is C++. I was wondering if anyone knows how I might be able to call a C++ function (fastcgi, rpc?) from the meteor server as a way of enhancing performance for a more compute intensive app.

Create a native module for node.js, then require and call it like any other JS module, native or pure JS. Link: https://nodejs.org/api/addons.html
