Not a bad idea. I used the similar approach for Drag&Drop stuff. However...

Clear (or update) the clipboard whenever database is 
moved/dropped/whatever. Perhaps we could use the observer pattern to 
"monitor" the database that was once "copy"-ed and update the clipboard.

Although, this does not save much effort compared to implementing our 
own clipboard.
