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.
