Is it possible to use NPM private modules in a meteor package? From what I can tell the answer is no, it looks like the @username/packagename scoping chokes something up. But there was a somewhat unclear issue that referenced it, so it seemed worth asking.
Meteor 1.3, which should have a beta release out any day now, will let you install NPM libraries in a node_modules subdirectory of your app or package, just like with vanilla Node apps. So you can run npm install however you want to get your modules there (including private modules).
