I SPENT TWO DAYS drinking Citrix Kool-Aid in the pleasant surroundings of the Edinburgh International Conference Centre and emerged into a fresh summer shower with the belief that the next great platform for the internet will be built on virtual properties, not on the backs of towering web-enabled platforms. I use a lot of web platforms--software code behind Six Apart's servers, communications platforms that don't scale well, and online shopping carts that often fail in epic ways. In an industry fueled by racks of servers and legions of corporate users, big giants like IBM and Microsoft can easily lose their perch points when pure web players like Google enter the game. The successful newbies don't just slice up market share. The game-changers just push everyone aside like Google did to AltaVista, Yahoo! and Excite.
