Hmm, I dropped off the IETF announce lists a few years ago so I have missed this fairly significant change. One thing I noticed though was that this script doesn't comply with the mentioned RFC. I am guessing it may have been written against an earlier draft (yep, the script says Sept. 2004). While it creates a pseudo-random address, a few problems I see are that it uses FD00::/8 as the prefix (instead of FC00::/7 which means it only tries to use half of the available space) and MD5 instead of SHA1 as the digest/randomizer. I know I am pedantic but one of the assumptions in this RFC (section 3.2.1) is that all generators of locally assigned global IDs use the same algorithm. It seems like it might be useful for me (or someone) to create an up-to-date version of this script over the Christmas break!
