Hi, all:

I co-chair the IETF "trans" working group, which is in the process
of developing a standards-track specification for certificate
transparency (logging).  We're trying to get a handle on the
potential impact of including serial numbers in precertificates.
Are there CAs who would otherwise implement CT but for whom
either needing to know the serial number of a certificate prior
to it being issued, or having to issue a certificate and precertificate
simultaneously would be 1) a complete non-starter, or 2)
excessively onerous?
