The current client available for windows is mostly just intended in assisting with the testing and development of the server suite. It is not 100% complete and the interface was compacted for testing purposes.
Development on it has slowed as there is hopes that someone out there has the time to either assist with its transformation into a complete product, or create a new one. It was written in Borland C++ Builder, and source is available.
It was written entirely by Sean Heber, please contact him with any offers to help with it's development.
