How to easily copy movies from Mac to multiple iPads?

I've got a Macbook Pro that I've been learning how to do some video editing with. I've also got an iPad. I know how to export the movie file to iTunes from iMovie so that i can view on my iPad.

My question is....

My dad also has a new iPad. What's the easiest way for me to copy/send these movie files to that he can view them on his iPad? Is there an app that we could use to copy them from one device to another wirelessly? I know we could probably use home sharing, but I'd like to find a solution where I could copy the movies to his iPad and he wouldn't have to be in range of my network to view, etc.
