I've just refreshed my HTTP Cookie and Cache related Internet Drafts. The drafts have been discussed here a couple of times before, but to summarize:
draft-pettersen-dns-cookie-validate-03.txt (archive)
This Draft describes Opera's current heuristical approach to avoid sending cookies to registry-like domains like co.uk (The "Cookie Monster Bug"). First discussed here.
draft-pettersen-subtld-structure-03.txt (archive)
This Draft describes an improved approach to handling the "Cookie Monster Bug", using an online black list of registry-like domains. Also first discussed here.
The Mozilla team's work on "Effective TLDs" is based on an early version of this suggestion.
draft-pettersen-cookie-v2-02.txt (archive)
This Draft describes the ideal solution to the "Cookie Monster Bug", that everybody starts using a new format for cookies that completely remove the problem. First discussed here.
draft-pettersen-cache-context-02.txt (archive)
This Draft describes a method for giving sites a method to tell the client that a group of webpages are related, which can be used to better organize logouts. First discussed here.

Yngve: are there lessons to be learned for Effective TLDs here? I had a look through your new draft, but couldn’t see anything immediate…Gerv
The major difference between the first subtld draft, and the current one, is that the newest one uses an XML based format which is more flexible than the original text format, and not as complex as that one.
