This fascinates me, also. Wasn't there supposed to be a kind of 
Magic Bind of Elves to the homes of their master's? Whatever it was 
it appears either to be weak, or weakened.

I wonder if the determination of Dobby to do right by Harry 
Potter "broke" it, or the eventual reward of freedom that Harry gave 
to Dobby in return?
