Now that OS 3.0 supports calendar subscriptions and CalDAV, why don't those types of calendars in iCal sync as such? They sync as regular calendars, when it would make more sense for them to be added to the iPhone as a subscription or CalDAV. Is there a good reason this isn't how it's done? Is it going to be done in the future? Along the same lines, why can't LDAP be synced through iTunes, since it can now exist in both OS X and iPhone?
