In terms of publication interest, back in the fall Jari Arkko had
announced a program to encourage widely implemented EAP methods to
publish their specifications as RFCs. As I recall, there was
interest to publish EAP-FAST (in the RFC Editor queue), PEAPv0
(documentation currently being revised for submission as an Internet
Draft). I don't know the current status of the EAP-TTLSv0
publication effort (e.g. whether publication has been requested or
not). Steve Hanna might know.
In terms of history, EAP-TTLSv0 was accepted as a Standards Track
work item of the PPPEXT WG prior to the formation of the EAP WG. It
has been implemented on a wide variety of platforms including open
source versions for Windows (http://www.securew2.com/) and Linux
(http://open1x.sourceforge.net/). Interoperability of EAP-TTLSv0
implementations is currently certified by the WFA.
In terms of features that would be needed to meet EMU WG
requirements, I think we are probably talking about crypto-binding
and channel binding. It is possible that there may be other
features needed for some scenarios (e.g. mutual certificate
authentication for a device/machine plus user auth for scenarios
currently discussed within WiMAX Forum and 3GPP2).
