Right now, this adds a Meteor method that lets you create a new Meteor account by email. The Drupal module uses this method to create new accounts.
I want to develop this further, and the roadmap is wide open. Please open issues for the integration features you would like to see.
I will be using this in Spendflow eventually.

Thanks to Project Ricochet for allowing me to adapt and publish the code Pushpin Planner uses to create Meteor accounts from Drupal.
