I have posted a rather inelegant Solution to getting info from Now into ICal;amp;start=20

However this uses Palm Desktop in order to get the data to a Vcal file.

Hey Now guys, I know that you are working hard on Nighthawk, can you put together a kludge that will allow us to take calendar info and export it directly to Vcal without having to use Palm? Either that can you help some of us applescripters out there to write something so that we can start using our Iphones with your current software?

While it isn't as grand as shipping nighthawk, it does win you some major public relations points!
