This is interesting news. My use case is indeed having many subdomains together with a wildcard DNS like '*.somesite.com', and I'm not designing some nefarious plot to redirect 'notexistant.somesite.com' to an ad-serving site. Instead, a page saying 'this subdomain can't be found', together with a registration form, would be shown. (Speculation mode on) Would Google penalize this setup with a lower Pagerank?
