How do you store data server side that is specific to a client in Meteor?

Question

Express implements a server side session object that lets you store data specific to a client. How would you do the equivalent in Meteor?

I think a "meteor" way to do this is:

On server side create and publish a ClientSession collection

UserSession = new Meteor.Collection("user_sessions");

Meteor.publish('user_sessions', function (user) {

    return UserSession.find(user);    
});

On client side

Session.set('user_id', 42);

UserSession = new Meteor.Collection("user_sessions");
Meteor.subscribe('user_sessions', Session.get('user_id'));

You now have an application-level UserSession object that is specific to that user that you can put/get stuff.

Also, you can manipulate the UserSession collection on the server using Meteor#methods.
