Well if you stick to straight html/javascript you'll have zero control over external devices (beyond what is provided by javascript APIs supported by the browser, eg the geolocation api gives you access to location data from gps units). If you wrote a browser plugin, that plugin would just be native C/C++ code and would be able to do anything native code on that platform can do. Your plugin and your webpage can communicate via javascript too.
