In the bad old days when I had to use a WIN box, I would Sync my Mac's iCal with my Outlook via my Palm. Simply set up the Palm on the Mac to use iCal instead of the default Palm software. Then for the PC set the Palm to use Outlook instead of the Palm software. Works perfectly.

Works perfectly for some .. until one or the other decides to duplicate all your calendar postings hehe. I've never had great luck with using a device across multiple machines for stuff like this. Even my cell phone, which only syncs with iSync ends up duplicating entries over and over again. Hopefully one of these years someone will get it right and things will "just work" (not holding my breath on that one hehe).
