As I went on to say:

"It is probably fair to assume that CT logs will be maintained by CAs
but it would be entirely practical for an open service to be
established. The criteria are rather simpler to enforce than
certificate issue."

I don't see the CAs running CT logs as being necessarily exclusive.

In particular, running a CT log does not require audit which is the
difficult part of being a CA. The whole point of transparency is that
the operation of the log does not need a trusted auditor with special
access. Anyone can audit the operation of the log.

Now what the non-CA application does call for is thinking through a
lot more of the operation of the logs and how they are held
accountable.

True and that concern has already been an issue with zones such as
vb.ly which was grabbed back when the value of the zone was realized.
