Meteor internals, get template HTML outside of application context?

I want to have a CLI, where I need to extract the internals of an HTML template in some way. So far, I figured I could use var fs = Npm.require('fs');, but cannot access the Template paths, which makes that worthless.

What I really want is to render a template without the application, if that makes sense. This is because I want a CLI command that sends HTML in its request.

Has anyone experienced this? Any suggestions?
