At IETF#89 in London many IETF participants met to discuss potential new work on authentication 
and authorization for constrained environments and lots of positive feedback during the BOF was 
received, see http://www.ietf.org/mail-archive/web/ace/current/msg00309.html 

Following the IETF meeting the charter discussions continued to address various questions that 
surfaced during the BOF and discussion can be followed at:

The charter discussions was concluded at April 28, 2014 and the outcome was handedover to the IESG as input for forming a new 
working group. The offical chartering process started, and the charter is now in "Informal Review" state, for comment by the IAB 
and IESG: https://datatracker.ietf.org/doc/charter-ietf-ace/

During the chartering process, the committee has to decide whether this belongs in the App Area or the Sec Area. First feedback is 
expected for end of May 2014.
