I have a similar project that attacks this problem from a different angle: http://deployanything.com
I find direct transfer really convenient and preferable to dropbox for certain things (like large files that you only need to send once and to one person). I could see something like you're doing being helped by being built into a chrome plug-in or something so people can automatically receive. The angle of my project is being in the background and automatic, but giving the receivers full control over what types of things they want to accept.
Yes, it easily can be chrome plugin, or Java app. It is designed to be accessible from any modern device or browser, and I hope it is only question of time.
