community calls have also provided real-time, interactive feedback on candidate 
proposals, along with guidance on areas which need documentation before a 
formal proposal is made to xen-devel.   Such agenda items are typically covered 
after all series and priority topics have been addressed.

    I still think it would help if a short high level design would be posted
    on xen-devel first.
    
I think that is a valid point and I agree. In the past when we had similar
discussions often the outcome was not that clear and due to the nature of
the calls the discussions were also not well reflected in the notes.

So, there is an argument, that discussions typically are more productive when
there is the possibility for some preparation or an e-mail thread to refer to.
