will I need to have a Plug account to access my drives? Will I be able to access those drives from outside my house or office? Will my users/password for that account will be stored at some king of Plug centralized server?
> With Plug, all your devices are connected with each other thanks to a zero-configuration, private and encrypted VPN (asymmetric encryption based on RSA-2048/SHA-1 keys). We had excellent speed benchmarks on this network. It goes through any main NAT & firewall we tested, it's decentralized when possible, and it doesn't require any user configuration. It's safe and does the job.
> When Plug is installed on your computer, our application intercepts all the input/output operations performed on your files, using several patent pending technologies. When Mac OS X, Windows or Linux want to store or access data, they ask our application instead of manipulating the hard drive. When needed these operations are redirected to Plug. Thanks to this, we give you the best experience possible. We show in your OS all the files you have in your Plug, even if they're not actually in your computer. We use your local storage memory as a cache, to store both the files recently used and the ones you want to keep for offline-viewing.
I don't blame you for not knowing what the heck it is; I had to plough through a bunch of nonsense to find the above two paragraphs.
So, if you're a techie, it's "just a NAS". But if you're a non-techie, it's 100 times more useful than a NAS.
One hopes these are their patents, that they aren't granted, etc.
