Spicebird was created by a group called Synovel Technologies,
“an opensource technology startup based in Hyderabad, India. They
develop and contribute to Free and Open Source applications, especially
in the enterprise communication and collaboration space.”

is a collection of contact and collaboration tools, including Chat,
Email, Calendar, Tasks and Contacts. What’s nice about the integrative
approach to these tools is that, for example, you can check on a
contact, and not only do you get basic contact information, you also
see your contact’s online status, so you can IM this user via the
built-in Chat window, or contact him via Jabber, if you choose. The
application is built on top of mozilla Thunderbird, Sunbird, Xmpp4moz
and adds more features and integration. The extensibility of the
mozilla platform makes adding new tools and customization of the suite
easy. Spicebird has a long road ahead to become a comprehensive
communications suite.
