+1. It gets even more difficult for relations but people are actually 
starting to use the /browse/relation/xyz URL as a permalink - lots of 
times on the Wiki, but also externally. If I were just a little bit more 
evil than I actually am, I'd make it a habit to delete and re-create a 
few relations every day just to drive home the message that IDs are not 
permanent. But I can offer them no alternative, currently.

I think it has been successfully used in re-importing/updating opengeodb 
data in Germany and maybe other parts of Europe. But these were just 
place nodes. They even had a special tag, openGeoDB:auto_update, that 
would list which tags would be eligible for later sync.
