(Need Fast!) Text Field that will save entered information and fill out another (Contact Form 7) field

I want to have a page with a text field for a name, when someone enters their name, I want the text field to save it there eternally. This should be very simple. Next, I want the saved information from that text field to populate a separate text field on another page. This is all very straightforward, but for a partial demonstration of what I need, see here: [login to view URL] By entering your information in that comment name area and whatnot, it can be saved, I want this done automatically however, and with the added ability to populate another text field. If the latter is too difficult or not possible, I would be satisfied with just the former, having the text field saving the information forever using cookies.
