Another NV+ v2 vs Ultra 4 question

OK I've finally gone and bought the NV+ v2 ... at the end of the day, it looks like to get what I want (encrypted storage, fast network access, fast dump and restore to USB 3.0, relatively seamless remote access) I'd either need to do a pile of hacking of an Ultra, buy a high end QNap ... or buy an NV+ v2 just as a nice decently fast NAS with a few Truecrypt containers on it that I can connect to over the local network and use the Linux server (which I already have anyway, stays on all the time and which cost me $50) to handle all of the exotic stuff (such as on-the-fly decryption for remote access and dumping to/from the portable drive via its USB 3.0 port).

Now let's see if I'm right. ;-P
