Siva's webtop: All under Sun.

I am using Thunderbird as my email client, as the UI is consistent across all platforms (Solaris/sparc, Linux/x86, Mac/PPC). Till now, it was missing integration with Sun's calendar server. Many times I started up Evolution when I needed to work with meeting appointments.
Now there is a solution (at least for Linux & Mac). Enter Mozilla Lightning. The lightning-wcap.xpi has to be downloaded and using Thunderbird's install tool, installed this addon. After restarting Thunderbird, now I am able to use Thunderbird to my mail as well as calendar client.
Now, what would it make to make a Solaris/sparc, Solaris/x86 equivalent of lightning-wcap.xpi? Any volunteers? I will post more on this later, after attempting for Solaris.
