World PvP Interactive map ?

Would be really useful and immersive to have a map of the "current political state of the world" for each regions, with colors to symbolize what factions control which regions and where are the main PvP clash occuring at the moment etc.. All this available on the Warmane website.
Im especially thinking about Icecrown where regions often change hand and that it would motivate and help players who'd like to participate in the World PvP.

What do you think of it ? Is it already existing ? ^^
