I have been watching this thread with interest as I am trying to figure out the perfect home cloud system for myself.
As far as I have been able to find out, the CloudFTP will only transfer files from your iPad using apps. Goodreader has been used (PDF and Text) and I believe there will soon be a CloudFTP app. So really at the moment it's not much better than the GoFlex Satellite.
I like the flexibility of the PogoPlug over MyBookLive, by that I mean I can add different usb storage devices. But ultimately I'm looking for home cloud storage that allows file upload/download from any device.
Think I'll have to dust off my old linux handbook.
