There's no completely free solution for this. You'd either have to write your own server (time cost) and run it out of your home, deploy a server to some other cloud service (not free), or use a service like Urban Airship (not free).
The good news is that Urban Airship offers a lot of free messages per month (can't remember how many), so you could at least get started using their service. They have a really nice REST API that works really well with something like App Engine. Also, I'm pretty sure that even if your app was wildly successful a couple of AdMob ads in the app would cover the cost of using something like Urban Airship. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
