At RunRevLive I used an updated version of the Data Grid with built-in  
support for drag reordering and setting the dragImage for drag/drop.

http://tr.im/data_grid

I haven't documented it yet but starting a drag and drop operation  
with the row being dragged on displayed as the dragImage is really easy:

##
## Data Grid Group Script
##
on dragStart
     ## use current row as dragImage
     put the dgIndex of the dgDataControl of the target into theIndex
     set the dgDragImageIndex of me to theIndex

     ## Set dragData to start drag operation
     set the dragData["private"] to "My Data"
end dragStart
