If you're willing to leverage GPLv2 source, see
http://www.sacredchao.net/quodlibet/browser/trunk/quodlibet/qltk/views.py
for the MultiDragTreeView class - you may want to change out what it
draws in __begin, but other than that it should be nearly drop-in.
There's some other goodies in that file if you like them.
