Anyone know about ABGP for propagating AppleTalk routing information?

@Tashtari pointed out that the AppleTalk Control Protocol for PPP (in RFC1378) mentions that RTMP, AURP, or ABGP are options for exchanging routing information.

As a full-time BGP nerd, the mention of ABGP made my ears prick up, but what the hell is it?

In the 22nd IETF Proceedings we find:

ABGP

A presentation was madeon the possibility of introducing a BGP like protocol as a border
gateway protocol for AppleTalk. Greg Bruell from Shiva made the presentation, Yakov
Rekhter (IBM) and Scott Brim (Cornell) were in attendance. Why BGP? It looks a
like AURP when you make some needed extensions to BGP to incorporate AppleTalk.
Transport stays the same as BGP except that it uses a different TCP Port. Message layer
stays the same as BGP, the autonomous system number maps to the domain identifier and
there is a change to the network list into the network zone tuple list. Some advantages are
that BGPis a well known implementation, decisions on policy are outside of the update
protocol and it is easy to implement.

I wonder if this played a minor historical role in the design of the multiprotocol BGP we have these days; Rekhter, in what I assume is a future job at Juniper, was one of the authors of RFC4760 (Multiprotocol Extensions for BGP-4) in 2007.

Does anyone know if this actually shipped in anything? I'd love to have a look at it.
