Definitely was not implying the wallet, but more along the lines of an IP. Your raise a good point though, that IP addresses might not carry sufficient weight/reliability.

I must focus on other things now, but I want to thank you for bringing this problem to the attention of the bitcoin community, even if they have chosen to ignore it and pretend that it's a non-issue.

I look forward to reading your followup paper (if and when you publish it). I hope you'll have a good solution in it.

(My brain is tempted to consider some using sort of stronger identity system than IP addresses [like Namecoin], but I really don't like that. That could potentially cause far more severe problems, especially if done incorrectly. And it seems like a hack.)
