Is there a chance that it'd be covered by some other patent?  Having 
recently looked at DH+password mechanisms, I'm wary of algorithms in 
fields where multiple overlapping patents already exist.

If it's truly unencumbered, I'd like to see this as standards-track.  I've
been working on an single-pass encrypt+MAC process draft for CMS for use 
in areas like EDI, but a combined mode of operation would be much nicer.
