Today Yahoo has announced acquisition of Zimbra. This is great news. Zimbra was a brilliant team with very good product. With Yahoo owning Zimbra, the product will have greater reach. Zimbra had an offline client, it will be interesting to see if Yahoo mail will have an offline version. Offline and desktop-web integration technologies will see increasing usage over coming years. Watch for Dekoh developer release soon :).
