Big request: Schema join (including AutoForm)

[AlexFrazer]

Let's say I have a simple database where there are Students and Classes. It would be very ideal if there was some kind of join where you could create a Schema that relates to other Schemas. For example,

StudentSchema = new SimpleSchema({
  name: { type: String },
  classes: [Schema({
    relationship: "Classes",
    max: 5,
    min: 1
  })]
});

So if you do Student.findOne(), it could look like this:

{
  name: "Steve",
  classes: [{
    name: "Calculus",
    department: "Math"
  }, {
    name: "Painting",
    department: "Art"
  }]
}

Would this be possible?

EDIT: I know you can kind of do it this way. Maybe it'd be nice to expedite the process.

classes: {
  type: [String],
  autoform: {
    options: function() {
      return Classes.find().map(function(doc) {
        return { label: doc.name, value: doc._id};
      })
    }
  }
}

This may be done someday in collection2, tracked here, and then autoform could also take advantage of these relationships as you describe.
