Hi,

Our submission is IOU (I owe you), a debt-tracking app.

The web page is at http://iou.epointsystem.org (links to follow)
I will upload example scenarios with screenshots in due course. The binary package is attached to the download page. Sources and build scripts are also available from the website.

Feel free to play with it! Feature request and bug report tickets are welcome.

Here are some deep links:
README with all the important info.
Download page with the latest sources and binaries.
