Airmule: Odd Name for a Real Service That Swears It's Not a Shipping Company.
Promising “affordable express shipping worldwide with trusted travelers,” Airmule urges potential customers to “ship with people, not boxes.” Translation: you give a stranger your package and they get on a flight with it, and then either deliver it in person or ship it using local mailing services to its final destination.
The reporter asks the obvious questions, and the founder of the company answers them, but there's no comment from the TSA or anyone else. I can't see this flying for long...if it's actually live for non-test users at all.
