I'm not entirely sure yet, but glancing around the docs, it seems like the way to do this is via their webhooks[1].

Agreed, that push is one of the more important components to a service like this.

Webhooks would address this challenge for a certain class of applications (those with their own server component), but if you imagine building a solid desktop email app (APNS/GCM not used), then you have a problem.

I'm glad they're thinking about it, though!

Yep, you can set up a webhook with `*` filter criteria, but I think OP was talking about a more specific notification system for the delta sync endpoint.
