Working Calendar setup on OS X leopard

After much searching and looking at alternatives, I gave up trying to integrate Leopard iCal with Google Calendar. It worked fine to just read the data, but not update the calendar. Maybe a few releases away then google may support CalDav, or someone interested enough in the combination may come up with a solution... There is a GCalDeamon http://gcaldaemon.sourceforge.net/usage12.html written in java that works well with google calendar, but the Leopard version of iCal uses a different format than the Tiger version, so this particular combination does not work :(. So, I switched to Thunderbird and Lightning (Sunbird) instead, and there it was quite straight forward to install and integrate with google. You have to enter some UNIX commands when doing so, but it is quite simple. Happy for now, but the configuration to also suport offline use is a bit more complicated, and something I will continue working on... Now I also have to figure out how to start the GCalDeamon as part of the OS x start up. (I am sure that is easy, but I have not done this before)
