Using GAE channels without browser

I want to write GAE based application that synchronizes information between computers/phones. Right now I am only querying periodically, which causes delays or requires user to click a button to refresh manually.

With GAE channels, it should be possible to do it this way that a device can be notified when it should refresh. However, since I want it to be a desktop app (not web app), I am wondering if I can write my own client to channel API? Or grab whatever's out there.

Is the protocol documented or are there clients available for anything other than JS?

There is now a Java implementation for the Channels API. It was just released days ago and is available via git at https://github.com/gvsumasl/jacc. I've also taken the liberty of forking it and providing a mavenized version at https://github.com/hatboyzero/jacc.

The only official interface is the Javascript client library. Although you could reverse-engineer how it works, since it's not a documented part of the interface, it could change at any time without notice.

If you're interfacing with Android phones or iPhones, each of them has a 'push' messaging API that you could use (Cloud to Device Messaging for Android, and Push Messaging for iPhone).
