We have used flash becuase flash is used by Google Ads and we use Google's ad distribution network to feed the ads. I've seen work by a research crew at UCSD who mounted an ad using iframes and javascript, but their usenix paper did not name their ad distribution network, so I am trying to see if we can target the non-flash platforms (i.e. Apple i* devices) using a different ad network. Parenthetically, I see my vanilla Mac (OSX 10.8.4) does not use extended UDP sizes in its queries to the local resolver, so it needs these local resolvers to pass back large queries using TCP.
