I got to play with one of these a week ago as I know one of the BETA testers. It's very cool... while I was taking photos in the house, she watched them get uploaded to her online site (her network was WPA protected... apparently there is OSX/Windows software to setup the password/key). It also connects to public wifi spots, but only if they don't require a login (so you can't use it at Panera, for example).
She said they were planning to add video uploads at some point. I'd assume that at that point they'd also include RAW, but I'm speculating. I dunno if there will be file size limitations, but I expect there would be.
I didn't get to play with it long enough to see how drastically it affects battery life, but I was impressed enough by its convenience that I'll be getting one.
