We don't want to require two-sided cards just to have secure
communications.  And yes, the text length is the point, I know how GPG
keysigning works. ;-)  but it also gave the designer trouble.  I'm not
saying that's the primary consideration, just that's why it's not there
already.  Furthermore, for it to be trusted, you also need to verify my
identity with some other trust relationship than my handing you a
business card.  If you're meeting me for the first time, that's not
sufficient.

All that aside, if we want the whole key fingerprint on the card, great
-- the code shouldn't be that hard to change to make this an option.
