Can I subscribe to Meteor Session for reactive template render updates?

Question

Is there a way to subscribe to the Meteor Session object so that a reactive template view automatically renders when data is .set on the Session object? Specifically the ke

While accessing the session object in this manner is doable .. You're not drinking the cool-aid.

In other words, Meteor excels in the respect of having publish/subscribe. Its not clear (to me) how much data you've got to put into the Session object before a browser crashes; I would rather not find out.

You would merely put all your session dependent code in a Deps.autorun() function to plug into subscriptions as mentioned in an earlier answer. Any time a session changes it'll modify the subscription; you can attach a ready callback, or use subscription.ready() checks to initiate specific actions, but ideally you'd structure your templates in a way that you could use rendered/destroyed functions, taking care to use {{isolate}}/{{constant}} when possible.

What you're getting at is kind of a difficult way to do something simple; and may not adhere to changes in meteor in the future; we can always be assured publish/subscribe will function as expected... Given Session is such a simple object.. whats to say someone designs something better shortly.. and it gets merged into meteor; and you're left with some weird workflow based on custom objects that may not break the Session; but may impact other parts of your interface.
