[wg-all] [ogf-board] Request for input for OGF submissions to the ITU-T Joint Coordination Activity on Cloud Computing

Tue Dec 18 13:37:10 EST 2012

David,

Thanks for your update on these docs/efforts.  Imho, part of the theme 
of our response to ITU is to demonstrate that the OGF community 
understands federation management issues!
