We don't have plans inside Zimbra today to create a XUL version of our client. While we don't think every Zimbra user will only use the AJAX client we here at Zimbra use it extensively. There are many corporate environments where a fat client just won't cut it. However we do offer IMAP/POP and as we've said before are working on an Outlook provider, ActiveSync and Blackberry support.
That said if the community has it's heart set on a XUL app our SOAP api's would make this pretty easy to build. Take a look at ZimbraServer/docs/soap.txt, it's a good place to start. |
