your plugin is just great and I love it.
There is only one problem that I see when using a theme in a mobile device: the height of the content is set with the height of the first element in the list of elements and this is not always true.
I've modified a little bit the innerfade.js file and you can find it here: http://pastebin.com/hGx3aEu1. I've added a variable called "biggestHeight" that takes the biggest height.
I hope you update the code.
