>and a rebuttal to it from an expert in the field.

while i agree with filippo, the way you worded this makes me think that you may not be aware that gutmann is also an expert in the field. so, if you are giving filippo weight because he is an expert, it is worth giving some amount to gutmann as well.

Damn. It's like I insulted Vault.

Also, I went over Filippo's post again and still can't see where it references the Gutmann / Neuhaus paper. Are we talking about the same post?
