As an end-user, I'm hoping to eventually see an OCCI-aware ElasticFox
(or similar cloud infrastructure provider dashboard) that can be used
to view and manage OCCI deployments. (This may just map to a
collection of use cases.)

That sounds like a great use case - please add it to the wiki! I'm considering similar things for Windows (having already done something like this for Google Apps).

You've raised some interesting points which I'll split into separate threads.
