Lorename (and @!~) only applies to items at the moment, I could look into naming blocks (by location) & entities (by entity unique ID) internally (although 1.5 will have true named entities).

Naming blocks seems kinda pointless to me, except for containers, which as I recall do have names (this might be new in 1.5).

In 1.5 names will now display above mobs heads, Using THIS on a zombie from player could pull the player name.

That kinda subverts the meaning of THIS. Maybe a new special keyword like THISNAME? That would also make it possible to transfer names between mobs of the same type, though I'm not sure why you'd want to do that...
