BeatBox - Dropbox mobile file sharing app

I just released the first version of BeatBox, an android app for (in person) Dropbox - to - Dropbox file sharing. Log in with your Dropbox username/password, browse your files, choose one to send, and Bump phones together to connect with the person you'd like to send it to - once they've agreed, the file is copied to the BeatBox folder in their dropbox. This way, you can share videos, music, documents, or whatever files you'd like from your dropbox - without downloading them to your phone.
The connection is through Bump, which if you're not familiar is basically a way to connect two phones by physically bumping them - so you can only send to someone in person. I hope it'll be useful if you want to transfer larger files (pictures, mp3's, movies) with only mobile access...

There's a free version, BeatBox Lite, which can only send files of 250KB or less, while the full version allows transfers up to 300MB.

Of course, I'd love to hear comments/bug reports/criticisms/suggestions!
