This is still a rumor at this point, but many folks are speculating that the iPad Camera Connection Kit might be able to allow USB audio output, since it’s offering you a USB port anyways. If that’s true, it would be rather interesting, as you might even be able to hook up some useful devices to the iPad. Another possible use would be if you were able to charge your USB devices from it, such as your Mifi. Of course, that sounds a little bit like wishful thinking, but when you take into account a Mifi has about 4-6 hours of battery life and the iPad has 10 hours, sharing might actually be caring, wouldn’t you think?
