    I would be very interested in how you expect someone to navigate through
a list that has >100,000 items.  I really strikes me that you should rethink 
this use of the list manager.  Make it Hierarchical like the SFdialog.
Other wise it would take >1000 clicks in the scroll bar (moving a page
assuming 100 elements on screen at once).  or an accuracy of about 200 elements
(two screens) by dragging the scroll bar thumb (this is down to the pixel).
I would think that this would be very unusable.
