This probably isn't possible, but I thought I should ask just incase I'm wrong.  Is it possible to connect 2 or more laptops together and drag files/folders from one screen to the other as if you were using a dual/triple/quad head graphics card on a single computer?I'm using Ubuntu 10.04.
Connect 2 laptops together in dualhead mode?

Synergy comes close by letting your mouse pointer cross monitor and machine boundaries.  Not sure if there's a way for drag-and-drop'ing files...(I faintly remember some support in synergy, though...could be wrong Edit: I am wrong.)You could just use a shared folder, I suppose.
