So here's an initial drop of the code at the googlecode project:

I haven't figured out an easy way to get it hooked into the windows installer, but if you're running with Apache on linux then it should be easy to follow the instructions to get it up and running. There are a few known issues but feel free to file suggestions and bugs on the site and I'll do my best to keep on top of them.
At the moment Chrome and Firefox are known to work. I've not tested with other browsers. I'd be interested to hear if people find bugs or confirm if it works out of the box.
To be honest I don't expect it to work on an ipad as touch events don't map to mouse click events. I'll see if I can make an ipad friendly version in the future.
