Has anyone figured out how the automatic download of subscription content works?

It's my impression that the radio is not on in any mode other than fully-awake (when you wake the device up from sleep, the signal strength indicator always starts out at zero), so it's unlikely that Amazon initiates connections to the device to deliver content.

My guess at the moment is that the Kindle will periodically (no pun intended) wake up and polls for new content.

If this is the case, I'm curious as to how often it does so, and from what modes (sleep vs. power switch off) it will do it from.

One possibility is that when you subscribe to a newspaper or blog, that the subscription data includes information about when the Kindle should look for new content. So a blog might be set to once an hour and a newspaper might be set to 3am once a day. This would allow optimizing battery life for people without active subscriptions, and let Amazon optimize when their servers get hit with requests and how much they have to pay for wireless costs. But it's probably fancier than the service is at the moment.
