Another option is to write the iOS application directly to the MongoDB instance used by your Meteor application. You can use any MongoDB driver, for example NuMongoDB . The meteor exchanges MongoDB databases monthly every ten seconds, so Internet users will automatically see updates, albeit with a slight lag.
DDP is developing rapidly, as Tim said, so this option can be a little more stable.
In terms of hosting for scalability, I recommend separating the MongoDB instance from the free meteor.com website using a Mongolian host such as MongoHQ.
