I have also been following a lead. I have made a local copy of the website (right before the site went down). The live chat functionality used in TimeToBit seems to be custom made because there isn't any copyright on it (javascripts, stylesheets, etc.) and there is a very limited set of sites using it (read, indexed by Google). I'm trying to find out who has developed the other sites and see if there is any match from what we already know.
