[VOIPSEC] SIP with Kerberos

[Muhammad Ali Syed]

Hi All,
I was wondering Can anyone point out any recent draft (or standard) describing usage of Kerberos (for authentication and encryption ) for SIP
It seems all we have is  draft-wagle-sip-kerbpki-00.txt, which is quite old and expired one 
http://old.iptel.org/ietf/allsipdir/draft-wagle-sip-kerbpki-00.txt

What are the show stoppers for using Kerberos for SIP ?

Your thoughts   ????
