      This is not true for all plugin technologies. A lot of plugins for IE
      (ActiveX plugins) use WinInet API directly to access to Internet
      files. In these cases, the IE browser does not know nothing about
      plugin's requests.

      Browser security policies, are used to allow or disable the plugins
      execution, BUT only that. When the plugin runs, all data requested by
      the plugin is managed only by the plugin. To give you an example, the
      restriction of shockwave to load local data only from "dswmedia"
      folder, is a restriction made in the plugin, not in the browser, the
      browser never blocks any data, in local or in Internet.

      The problem with Flash was that some vulnerabilities was discovered in
      Flash5 core, and a SWF conveniently manipulated by a expert cracker,
      could allow to run a virus in the browser. So, if QT uses Flash5 core,
      maybe Apple decided to disable SWF by default. This could be solved if
      QT integrates the latest Flash core, but Adobe does not license its
      Flash source code since 7.0 version.
