I quite agree, that this idea is more problematic. However, we are still giving it a try, since some sites simply do not offer a protected login at all, or at least we haven't found one, e.g. Washington Mutual (WaMu) <http://wamu.com/securityandprivacy/security.asp#Phishing>,

Really?

How about:

But, if you do find some without secure login forms, I think the right approach here is to shame them into submission. There's only so much you can do to compensate for their inadequacies.

BTW, I found the above two by viewing the HTML source and messing around accessing some of the URLs or domains in the form without any parameters.

Also note, that while this idea is problematic without any help from the servers, the idea could work quite well to authenticate pages if the server cooperates and provides e.g. signature on the page;

How could you prevent compromise of the signature if the page was compromised?

The last-modified in HTTP header is not secure so we can't rely on it...
But yes, I agree this is not so user friendly. Well, we are doing research, so we can do some imperfect stuff (ok even lousy stuff), maybe we or others see how to improve it, and we can always remove it.

Sure - absolutely. This is supposed to be constructive criticism :-)
