So I had this brainstorm that I could get sticky labels approximately the right size and paste current gpg key info to the back of business cards. I played with glabels for a bit, but we didn't get along. I decided to hack something up based on the gpg-key2ps script in the signing-party package. I'm not proud of the current state; it is hard-coded for one particular kind of labels I have on my desk, but it should be easy to polish if anyone thinks this is and idea worth pursuing. The output looks like this. Note that the boxes are just for debugging.
