That's cool.

Is there any examples out there on how to integrate it with a web-app as well?

What's the big advantage in relation to Parse? I love Heroku, but Parse seems like a really smooth solution for iOS/Mac.

I think this and Parse are cool.

This looks better for getting started quickly if you have a Core Data app. It should also be easier to customise although Parse can do more for you (user registration is built in) but you need to be on the paid ($199/month) package to use your own branded login I think.

Also I can't quite tell but it might be possible to take the Heroku buildpack and deploy it on your own servers so i think you would have easier options to migrate away without a rebuild. This is worth something to me.

One possible advantage would be to touch the ecosystem outside of Apple.

Parse has first-party SDKs for Windows Phone, OS X, iOS, JS, and Android. There are third-party interfaces for many languages (PHP, Ruby, etc). It's not an Apple-only solution.

What do you mean by this?

I watched the video. How does one add user account support? For example to handle multiple users in your example task app.
