And that depends on the direction of development we want to take.
Do we want nvme-cli to become a 'general' nvme management tool, then
we should investigate in having an spdk plugin.
Or do we want to have nvme-cli as the cli for the linux nvme kernel 
driver, then clearly we wouldn't need an spdk plugin.
That, I guess, is the real discussion.

Personally I would vote for the first option. But I'm sure others have
other opinions.

Cheers,
