i think the fact that they put a digital signature of any kind on the paper transcript is pretty cool. would be kinda neat if there were a combined standard where there were a deterministic scheme for ocr'ing the text (specifically its ordering) as well as an accompanying signature so that the signature actually signed the text that appears on the document.
There are a few applications that do that - but it is a patent minefield, courtesy of the biggest patent troll in history:
