some browsers implement HE, which is useful.  TB handles some types of 
connection failures, but there are plenty of other failure modes which 
it cannot handle well (e.g. partial connectivity).  I suspect there are 
dragons down this route, starting out with how we might consider 
defining standardised APIs for reliable connection semantics to handle 
transport failures.  I.e. HE + lots more, cross-platform, cross-application.
