In Cloud to Device Messaging (C2DM), your server pushes a message to Google's server, which then pushes it to the device. The message is a small one that simply points to something else (eg. "you have new messages"). Your app receives that message and then does whatever it wants. With the current problems around the Sony e-reader iOS app and having to shift things around to allow something like The Daily, maybe Honeycomb tablets (if they sell well) will be seen by publishers as easier and more attractive (because publishers keep subscription data) to develop for. With C2DM, it's easy to deliver a weekly or monthly magazine in the background as soon as it's available, but without constant polling. And now there's a standard in-app purchase system, or I guess you could implement your own.
