To finish on the VTODO with DUE date topic, I've looked at some "not yet CalDAV enabled" clients.
In Outlook (more precisely, in Outlook 2003), you can create a task with a start and/or due date (no time). This task can have an associated alarm, which is specified as a date and time. This removes the ambiguity of using relative alarms, found in both Apple iCal and Lightning. It also allows to have a task with no start or due date and just an alarm.
Using the eM Client , you can also create tasks. Both start and due date/time must be specified. This task can have an associated alarm, specified as a date and time.
Note: the eM client is CalDAV enabled for VEVENT but not yet for VTODOs.
Evolution offers all combinations of start/due, using either date or date and time. Nevertheless, I could not find a way to set an alarm which is quite strange.

The Sun Convergence web client exposes only an optional due date (or date time). The associated email or sms alarm can be either relative or absolute ("On Date" in the pulldown below):
