I have to apologize for that message; I was totally confused particularly in the second part where I discussed the impact of an MD5 preimage break on HMAC-MD5. What I described was completely wrong and had nothing to do with an attack on HMAC-MD5. Luckily the message was so long and poorly written that hopefully few people were able to follow it well enough to be misled. Again, apologies.
