What ever happened to... MARP (Multi-Access Reachability Protocol)

Last draft appeared to be

which expired Sept 2003 (Abstract: defines a protocol to quickly determine
the existence or aliveness of devices attached to a shared media
(broadcast) subnet.)

First read about it in this presentation, where it was billed as an 
alternative to fast hellos:

The idea was that a switch could notify connected routers of link failures 
immediately - there would be no need to wait for the dead and hold-timers 
to expire.

Is this idea still flying? There appears to be very little on the net 
about it, except what I've mentioned above.
