This is neat idea to market, First create a CUIL clone in terms of appearance.Second bring it down, so people who missed it (including me) want to see it and Then relaunch it again with a new name :-) ....
I'm just guessing, but 4hoursearch.com is probably much more available and/or cheaper than yuil.com, as well as being easier to remember than sampullara.appspot.com/yuil/. Just guessin'.
