Answer 1

It might be a bit too late, but I wrote a Mongoose plugin to perform deep population at any arbitrary nested levels. With this plugin registered, you can populate category's articles and accounts with just a single line:

Category.deepPopulate(categories, 'articles.account', cb)

You can also specify populate options to control things like limit, select... for each populated path. Checkout the plugin documentation for more information.
