With your U3 smart drive, you can just plug into any PC running Windows, and use the System Access screen reader, access your email, scan documents if a scanner is attached to the computer, from home, or anywhere that you have access to the Internet!
Just access it from the preferences page by activating the Manage My HomeServer option. Important, if you stop, and or remove the HomeServer service from your PC, you will not be able to access your home computer remotely.
