This is the premise of the Mill architecture; though I haven't heard from them for a while now.
I'm also curious about the state of the Mill - judging by the forums on their website they've been basically dark for about a year and a half now, though Ivan Godard claims that everything is still moving along, just slightly slower than expected.
