There were some old (expired) drafts on this subject named:

draft-mrw-abfab-multihop-fed-02, and
draft-mrw-abfab-trust-router-02.

However, things have moved along a bit since then.  The latest docs and code are being developed as part of the Moonshot open source project found here:  

https:/wiki.moonshot.ja.net/

We tried to bring the Trust Identity Protocol (the transitive trust protocol) and the Trust Router Protocol (the routing protocol that is used to choose a path of transitive trust across a federation) to the IETF a couple of years ago, but at that time we were only piloting the technology in the UK and there wasn't much interested from anyone but European universities and associated entities.  Stephen Farrell didn't want to charter the work without interest from the commercial sector, so we have been working on this outside of the IETF since then.

The work has matured significantly since the drafts were last updated.  We have an operational Moonshot federation among universities in the UK (using a single Trust Router), and we are piloting a European-wide federation with multiple Trust Routers over the next year.  Once we have a multi-Trust Router federation operational, we may come back to the IETF to see if there is greater interest in standardizing this work.

If you might be interested in following this work, let me know, and I will find out how you can joint he associated mailing lists.
