DatePicker

I'm trying to get a feel for the datepicker() UI widget but is feels a
little clumsy and not how i'm used to jquery working. What I want to
accomplish is to have the minDate of a datepicker be the value of
another datepicker.
So if I have dp1 and dp2 I would set dp1 to Feb 1 2009. When I
activate dp2 it should show the minimum selectable date of Feb 1
2009. Is this possible?
