   It sounds like we agree that looping *can* definitely be  
implemented in JavaScript, but that it can be very difficult to do so  
without visible/audible artifacts.

   I am not sure what you are saying about whether or not the media  
element should have an attribute to control looping. Are you saying  
that low-latency looping isn't a requirement so we don't need an  
attribute, or are you saying that we should have an attribute but we  
might not get low-latency looping with some media engines right now?  
Or are you saying something else completely?
