FYI ...

This may be very helpful... I have been looking for other java based open source POS projects that may have been started to integrated into zencart.

Apparently, there appears to be a good one that was started by a guy in 1995. The software was integrated into java as soon as it was good enough to incorporate. It has slowly been upgraded with technology over the years. You may want to check out these links. It would be a whole lot easier to merge 10 years of good work than start from scratch.

The interface also looks very nice.
