All, A lot of the existing compute drivers (15+) already implement start and stop node functionality via "ex_start_node" and "ex_stop_node" extension driver methods so I think it only makes sense to promote those methods to be part of the "standard" Libcloud compute API.
I've done just that in https://github.com/apache/libcloud/pull/1375. If there are no objections, I will merge it into master / trunk in the near future.
