Hi Matt,

It is not about identity federation (which is handled in Keystone), this is about resource federation across clouds, Nova resources are one of them.

I don't know much about Nova cells right now, I will try to understand it soon.

Thanks,
Arvind

Is this only identity (keystone) are other things like booting instances in nova from public/private clouds which are abstracted from the client, and if so have you heard of nova-cells?
