While researching this further today I discovered that the Open Cloud
Consortium <http://opencloudconsortium.org/> has a working
group<http://opencloudconsortium.org/working-groups.html>dedicated to
this topic:

That said, like many here I'm a "member" of the CCIF and this is the first
I've heard of this "collaborative activity". Tempted to sign up with OCC as
an "Expert" member <http://opencloudconsortium.org/membership.html> to find
out more but it doesn't look like one gets much access at this level.
