this is a topic that is difficult to exhaust ... very broadly described a lot of topics even touched on the subject of data security ... congratulations ... I would not diminish this unit that is a man and his laptop, it is impossible because the need for data storage is too huge no-one serious players do not need a small space and the computing power in home computers is too small not to mention data coding, it would take too long ... you could still write and comment, but I do not have time ... I'm really under the great impression of your effort, how much time did you spend to prepare it, read it with interest and I think that it is worth voting and sharing .... all good from @aple
