I think that's the right way to do it, this should be in the hands of 
the user and exposed as a preference in the browsers.
Although exposing (read only?) the user's preferred buffer setting to 
the HTML App/Plugin etc. would be a benefit I guess as the desired 
buffering could be communicated back to the streaming server for example 
for a better bandwidth utilization.
