James, thanks for the great article!
After implementing all your techniques I have a couple of questions, and it will be cool, if you can find a time to answer just some of them!
1) Is there a way to force a drop? I mean, without mouse, just like copy and paste an object into current host, without dragging it?
2) Is there a universal way for all hosts to catch a moment just before the drop happened? (Harbs suggested to use a before_place event, but as I can see it only works for InDesign).
3) When I dragged an image of BITMAP_FORMAT type, I even was able to drop it to Fireworks - but not into Flash Pro document. Flash just crashes! Is this is a known issue and maybe some workaround exists?
