AS map

Hi there, Is there any project of building a graphical AS map from BGP full route table snapshot? I remember seeing something like that on the web, but i can't find anything now that I need it :-) I also remember comment saying that sorting out the whole mess of BGP peers took weeks on a sparcstation5.. Anyone with an URL?? TIA, Cheers. -- Philippe Strauss, ingenieur systeme/reseau, Urbanet SA philippe.strauss@urbanet.ch tel +41 21 623 30 20 --
