Same here.

FWIW, the PKI-related and ASN.1-related code changes were the easy part 
for me.  It actually took me much, much longer to get my head around 
cURL's "multi interface" and implement the scattergun approach to 
logging certs and obtaining SCTs...

http://www.certificate-transparency.org/faq (emphasis mine)
"Will there be a limit on the number of trusted CT logs? Or will every 
CA that wants to run a trusted CT log be able to do so?
Increasing the number of CT logs increases the cost of monitoring for 
domains and auditors but we think “every major CA” is within limits of 
feasibility. However, CAs should protect themselves against collateral 
damage by also logging with third-party CT logs. *High performance can 
be achieved by sending parallel requests* to all commonly trusted CT 
logs and embedding the first n SCT responses."
