Hi, Michael, 29 is unassigned and available. Also, IMO, we should not shy away from using numbers that others are squatting on. E.g., 31-31 was only used by TCPCT in Internet Drafts; when it was released, it was implemented using 253 and AFAICT only in Linux versions that have since been cleaned up.
