Searching allinanchor: and allintext: on http://66.249.93.104 is returning VERY good results for my keywords - in some cases 50+ positions higher than google.com. Are these 'test' results a likely indication of where your site will eventually end up in the organic SERPs when google updates ... or simply a better set of results within the sandbox?
I believe Matt Cutt's from Google indicated in his blog that eventually Big Daddy will go live - but by then the algo will most likely have change some bit.
