1. The tech details are great. However, maybe not on the first page. I understood them, but do people that use for example Mozy.com know what RAID6 is? A picture is worth 1k words.
2. What are your typical upload/download speeds? What could I expect in terms of latency?
3. I would suggest that people set up their own encryption before they upload the file(s). I don't think many people have considered that as an option.
