Seems to work pretty well in Firefox 1.5, IE 6, and Opera 8.  Haven''t
tested any others yet.  All of these comments are based on testing it as
part of a Sortable, so they may not all apply to a regular Draggable.

One thing that I would personally prefer is to have it move the object
you are dragging by the amount it scrolls, so the item stays with the
mouse pointer.  It currently seems like it just catches up after you
stop scrolling, so it kind of jumps around sometimes.

Also, not all of the options are passed from a Sortable
(scrollSensitivity and scrollSpeed, specifically).

A cool option to add would be to have it start scrolling if any part of
the dragged item is beyond the view of the page (instead of basing it on
the position of the mouse).  I''ll see if I can''t come up with
a patch
for that.

Otherwise, looks pretty nice.  Much cleaner than my implementation that
I sent to the list a while back.

Cool! Please do investigate it.

The passing-through of the speed and sensitivity options should be  
more or less trivial, i guess.
