To be honest I didn’t look at internals of OpenStackClient but have some experience with Ironic client instead. Anyway, this is still a topic which need more discussion and investigation.

For the versioning we’ll have to use slightly different approach due to a different versioning in Fuel, I’m afraid. However, I agree that we should follow naming conventions and practices from other OpenStack projects in order to make it easier to other folks to dive in.

I would suggest using the Keystone client Session and authentication plugins if you want a stand-alone client as you will get SAML auth, and whatever else is being developed, for free. 

That sounds like a good idea.

I think this is not very reasonable because Fuel does not provide any service in OpenStack but instead allows to set up and manage OpenStack clusters.
