I use cal export, to provide view of and reminders for scheduled/end date tasks.
Cal sync, as you state, hasn't worked since the move to CalDAV - which I use with my Google Apps account. It's only use when it did work was same as above, for me.

Would be useful to have a way to easily add the exported cal to google/mobile me... I have cal view on iPhone and mac, but not from google calendar.
