I think this is remarkable and fun. You could certainly partner with a printing company to offer the ability to print them as business cards as well. Using something like:

You could possibly even offer the service yourself and accept the steem and dropship the cards as well. I know people have been looking for an easy way to design and print steemit business cards.

Vistaprint might even have an API. I know some printers have reseller accounts.
