I downloaded this unit from the Borland Pascal forum on CompuServe a few 
days ago and found that it almost did what I wanted...  Dragging multiple 
selections from one listbox to another.  All it lacked was the multiple 
part.  I have cleaned up the original source somewhat and derived a new
object from the original object that implements multiple selection dragging.
Hope this is useful to some of you out there.  

I have only a few problem with it now.  When dragging entries in single mode,
the highlighted selection continues to be updated as you move the cursor
over the listbox you are dragging from.  In multiple mode, it is very 
irritating because after you make your last selection, you have to remember
to keep the button down, since if you release it, you won't be in drag mode.
I am hoping to get it to act more like file manager so that when you press
the mouse button, it checks for selections and goes into drag mode if there
are some.  I will be working on this, but am kind of pressed for time now.
If someone else figures it out, PLEASE upload your solution for the rest of
us.  If not, I'll probably get to it in a few weeks.

If you have any questions, suggestions, complaints, etc., you can contact
me via CS E-Mail, or the Pascal forum messages.
