Automatically Generate Barcodes for Users on a Drupal Site

What is the problem?

As a conference organizer for a few of Florida's past DrupalCamps, and an attendee of many other conferences, I've noticed a huge bottleneck during the attendee registration process the day of the conferences.

nc -vnzu 1-65535 > udp-scan-results.txt

Perhaps a more revealing test would be to actually transfer a file using UDP.

The second volume from O'reilly Publishing wasn't what I expected it to be at all. Having not read the first book, I didn't know what it might contain. I received the book from the publisher for review and was actually pleasantly surprised by its contents.
