I aplaud your contribution. I've long waited something to sync with Outlook.

However in that wait, I've started exporing Windows 7 and linux (puppy linux) and cross platform applications like OpenOffice or in actuality Google. I've recently started using mCalendar. I believe they are working on a contacts program/screen to work with Google contacts. I don't know if your zSync would be able to work with their database, but that would be a huge leap! Alteratly if your 'zCal' would also have the ability to sync with Google. Hope this is somewhat helpful.
