Docuthentic says financial institutions mailed 40 billion financial documents in 2007, with an average cost of 2 dollars per mail.

VaultStreet is one of the providers of online storage space, online vault. They collect, organize their documents, and help you securely share their documents with their trusted advisors or contacts. Everything is centralized. I understand the concept, and reckon it would be useful to access all my important documents in an online repository.

In the last few months, many companies launched an online vault service: in the U.K., BT (Britishi Telecom) and O2 (one of the leading cellphone operators); in the U.S., Wells Fargo and its vSafe service.

I wonder whose role it is to help centralize those documents. A telecommunication company, a bank, or a third party? I can't wait to ask VaultStreet how their service compares to Wells Fargo new vSafe service.
