I've just posted a new version of the header extension encryption draft.  I believe this version resolves all open issues and comments from the mailing list and from the last IETF, including a resolution of the AEAD issue that David McGrew and I worked out in Montréal.  (For a full list of changes, see the "Changes" appendix in the draft.)

This version adds test vectors for the header extension encryption process; it'd be great if someone could independently double-check these for me.

Other than that, this is, as far as I know, ready for WGLC.  Note also that this is a dependency of the audio-levels drafts in AVTExt.
