Well, first off, we can throw out the ideas of juries because contract law is civil, not criminal. You'd be dealing with judges who are well-versed in the actual legal system, and would know that the mechanism of the signature is not what makes it legally binding. DocuSign adds comfort to non-lawyers, but really isn't going to make any difference in court.

And that is the actual business value - not legal, but administrative. Easy to send out, receive back, track who signed what, and when. The actual signature is a nifty feature, but isn't the business value.
