I am currently in the process of writing a money management application for the Zaurus that can sync with GnuCash on desktop Linux. Since I have also started on the Bluetooth GUI at the same time it may take a while to put together, but once I get the basic progam going then I intend to setup a Sourceforge project for it, so that others can add features if they want.

Initially ZCash will just be a companion to GnuCash, mainly for easy, portable data entry and so will not be fully featured. When I put it into Sourceforge, other features can be added if I get the time or if other people are interested enough.
