Gruber's point was that *lack* of autobuffer attribute should not be  
ignored. Webkit's eager autobuffering is a real problem.

I don't think that's a good use-case. Local file system should be as  
fast as cache and easily handle immediate playback. However if file://  
points to a network drive (sshfs, shared file server), autobuffering  
will waste bandwidth. If it's on a DVD disc, autobuffer may slow down  
loading of other resources (trashing due to long seek time).

I think the spec should say that browsers may ignore presence of  
autobuffer attribute, but must not autobuffer (from remote servers?)  
if attribute is not present.
