Will the Pogoplug operate with a password protected/locked (or encrypted) hard-drive and/or thumbdrive? I have to keep my drives secure from others but would really appreciate the ability to make them available online. I think most of the portable and thumbdrives come with security features so this should apply to many folks out there. I'm excited about the features of this device, but before I open the box I want to make sure I could still keep my local drives secure. Thanks very much.
