How does mobileme's idisk work? Does it use webdav? More specifically...how can it connect to your home computer and allow you to download any file on your computer from any other computer? Like this:

How do they get it to work in windows? Is it possible to connect to your home computer from anywhere with a web interface like they do without using mobileme?

Thanks for any clarification,

Matt

OK here is some clarification. That screenshot is not showing accessing files remotely from the home computer, it is showing a computer accessing the online iDisk storage. Macs can access iDisk directly from Finder, PCs can access it through a web interface.
