Hi Jay, Thanks for the update. Like you have noticed, version 0.9.0 which should be released in the upcoming days makes the default OpenStack driver work with trystack.org without needing to change the service_name attribute.
Which version of devstack are you using? It would be great if you could provide a reference to the docs which says that the new compute endpoint is now called "Compute Service". I think that the default endpoint in the current release is still named "nova" and that is why I will wait with merging your patch. In any case, I will add your example to the documentation - http://libcloud.apache.org/docs/compute-examples.html.
