Hi Harry,

I've actually just started working on a new revision of the draft in  
the last week; some side discussions at the APPS area arch workshop  
led me to believe that we may be able to make some progress on this.

I'll hopefully have something submitted in the next few days (once  
submissions are open again).

Cheers,
