If you have a workflow where you're happy for ALL your due items to appear in your calendar then OF can create an iCal ics file in your WebDAV account to which you can subscribe in iCal.

I periodically try it out then turn it off again because:

1) I have a lot of trivial items with due dates in OF and I don't want to see them all in the calendar, just some. No doubt I could avoid using so many due dates, but they work well for me.

2) All the exported tasks have "Due: " prepended to them so the text doesn't fit in iCal, which responds by lopping three characters of the end so it can add "...". That's 7 characters of my text that I can't see. Worse still, if I have overlapping items in my calendar, all the OmniFocus items become "Du..." which renders it useless for a quick glance.

3) The start date/time is ignored. All the items are of zero duration and have only a due time. Even if OF knows it starts at 1pm and finishes at 2pm it'll be a zero duration item at 2pm.

4) ALARMS! I have found no way of exporting the calendar without alarms. I'm exporting my due tasks to a calendar so I can use the calendar views to visualise what I'm doing and when, I don't necessarily want every event to be an alarm.

No doubt there are scripts galore that fix these issues on the desktop.
