In a discussion with Ken this morning, we realized that we hadn't mentioned to folks that the feature still works just fine as it did in the past. (With local calendars.)

Switching to the MobileMe servers converts all your existing calendars to an incompatible format, but you can still use iCal to make a new local one (File -> New Calendar -> On My Mac) and sync OmniFocus with that just as you have in the past. Sorry we didn't mention that earlier!

(We still have a feature request open for adding CalDAV support in a future version, of course.)
