Phillip, Iljitsch, If you beleive that there is an attack that SSL is vulnerable to you should bring it up in TLS. I think Iljitsch meant that TLS cannot protect against TCP vulnerabilities, such as spoofed connection resets. This is obviously well known. The upside of TLS has of course been

Eric, I was referring to Iljitsch's suggestion about SSL and IPsec, not the suggestion about DNSSEC. Yes. FWIW, I don't think that would be interesting. DNSSEC experiments by itself might be interesting, particularly if they could be combined with some movement in getting the root signed.
