Folks - Many of you have posted and indicated that you would be interested in working on the Sync4j connector for Funambol's server. We have some code from a earlier release of Zimbra and Funambol. This may or may not work with the latest release of each. Those that have signed a contrib agreement feel free to ping us when you have something to checkin and we'll get things setup in SVN.
