There already exist something like this in Scandinavia. I signed my mortgage papers electronically with a digital signature (of a pdf).
There is a government appointed 3rd party company that manages the signing keys (BankID). They implement APIs that others, such as banks, telecom and utility companies can integrate with to make use of digital signatures that are legally binding. The signed documents are stored by the service and the initiating party (the bank).
