Oh, and the WebKit implementation you linked to sometimes returns 
whatever value the embedding set on the object (thus punting the problem 
of what to return to the embedding), and by default seems to do this, if 
I read it right:

57	unsigned int NetworkInfoClientEfl::bandwidth() const
58	{
59	    notImplemented();
60	    return 10; // MB/s
61	}

(not exactly spec compliant, so much, of course).
