Even though iOS is sandboxed, has no files and no folders, lets not forget AirDrop on Mac doesn't do folders either. It almost looks like attachments: you drag (send) a file to the receiver. iOS handles mail attachments fine. I think this is something apple will implement later via software updates. Like for example obvious but long awaited OS X features like iBooks, Maps, Messages and Finder tabs. We're are wondering why they just didn't include it from the start, maybe they need a reason to sell OS X 10.10.

This seems like a possible win for Apple, and I hope they implement it. I just wanted to point out that OSX to iOS AirDrop is not as trivial as many people make it sound. There are edge cases, such as "what if the user doesn't have an app that supports this file?". It's different than email, because the file can't be saved in anyone's sandbox.

Realistically it could be done a la DropBox - i.e., another app (lets call it AirDrop) that receives these files and can launch the App associated with the file. Users could send the file through AirDrop.app by sending that file to AirDrop.
