Yep - I was more concerned that the difference was attached to the
validation process - we need an OV as this is a public facing IP. In
fact, we need to get onto their EPK program as there are to be many
cloud servers unattached to public domains. They will OV us once and we
can purchase unlimited certificates against that.
