If you're willing to wait for a client-server round trip to visibly see your changes, then sure. Otherwise, you'll need a way to temporarily (optimistically) change your in-browser data model with the updates while waiting for the server to commit your changes, then figure out a way to reconcile the server commit of v2 while you might have done v3 on the client in the meantime... Optimistic updates are not at all trivial. Meteor has a ton of code that basically runs an in-RAM version of MongoDB and keeps it in sync with the server.
