Dear colleagues,

The review has been posted to the CFRG mailing list.

P.S.: Ronald, I'll be happy to make an additional review after you finish
updating the SM2 I-D with design rationale and a summary of published
analysis results. Nevertheless, I've included my own summary of the
published results of SM2 to my review.

Best regards,
Stanislav
