Paying for too many drinks?

A friend and colleague, Sasha Gilenson is president of Evolven. Evolven has a product that takes detailed snapshots of server configuration across the enterprise that can be used to investigate and diagnose change. It can be used for daily audits of infrastructure to support stability and compliance. I was speaking with him today about the tool and I was thinking that it also may be very useful to take daily snapshots of cloud consumption to audit the financial statements of cloud vendors, i.e. Amazon or Rackspace. Here is the company website http://www.evolven.com/.   Do you think about this?
