I'm wondering if an approach as used by the OIPF video object (discussed  
during the workshop) for buffering would be applicable also in this case  
as a first "easy" step.
Basically you could let the application select which strategy to use (e.g.  
low latency, sustained playback) through an API call and control just few  
generic parameters (e.g. min/max bandwidth).

This will allow also a bit of differentiation/competition between  
different media players still leaving the application a bit of control of  
what's going on.
