Biggest problem with this solution is to trust VGS capability to secure our sensitive data. Which is a hardest thing to do in the first place. All it takes for a disgruntled employee(given company's practices cited in the posts below) siphoning out the data. They are really tiny enough to pay for the damage, making their liability claim render useless. However, given the trivial nature of this problem and interest, I decided to open source a solution which avoids liability concern.
