Actually it was stale, a leftover from during development - removed.

The user can name the PMD instance with socket ID if they so wish. The name of the PMD instance must already be unique - so we won't gain anything by adding socket ID there either... I'm not seeing value?

The socket ID is available to the application by reading   struct service_spec.

Removed - little value in seeing pointer values bar during development :)

Yes good idea - rte_service_is_running will return true if the service callback will be called by at least one service lcore - exactly what we need to check.

This check is implemented in v2, on the way soon. As noted in the first email, I'll kick off a mail about discussing how to best use service-cores, and how to enable applications benefit most from service cores (including not using them if they don't want to :)
