I have decided for my dissertation, with outside influence, that I will make an ecommerce system.

However, the problem with this idea is that it is common and not very interesting.

To ensure I get high enough marks, does anyone here have any ideas of how to make the system unique/revolutionary/groundbreaking?

I would like to implement AJAX/Atlas into the project, but the idea itself of ecommerce systems has been done before in dissertations.

Any ideas welcome!
