"We" are providing a large scale application in the education space, with more details to follow. I am not able to give much more now, but I can say that given the contractual nature of our application, we've been fortunate to start out with a HUGE user base that has taxed Meteor and exposed its scalability issues more than most typical Meteor apps at this time. It's still young, and there are some significant advances that can be made to its oplog driver, but overall Meteor is incredibly forward-thinking compared to other full-stack implementations. Philosophically speaking, you must be all-in, however, otherwise you will always kick against the goads. As everyone's favorite theologian would say.
