[cryptography] Auditable CAs

So my biggest question is what defines a "publically visible
certificate"? Of course every certificate gmail uses would be
public... but what about the cert that corresponds to the new product
google is launching that's in beta for a few users? That cert should
be published... but then that lets the cat out of the bag. (Isn't
this almost the same problem DNSSEC has?) I'm confused about whether
people opt-in, or opt-out, or opt-anything.

Wouldn't this be easier done with NameConstraints?
