First three are pretty trivial; last one is a bit of a pain, but doable if someone wants to poke me on IRC (/query Ironholds) and chat about what an unambiguous successful login action would look like in terms of requests. But I can do the first three in a jiffy.

Emphasis is "logged-in". If you guys want more solid overall numbers, I can get those in short order; this seems like a pretty critical question to have data on, fast. Lemme know.

If you can source some good reliable numbers, probably what we care about (all of which have been estimated to some degree in this thread already, I think?) is:

% of all requests from IE6
% of all https requests from IE6
% of all text/html https requests from IE6 (not so important IMHO, if it's difficult)
% of all logged-in https requests (or alternatively, % of all successful https login attempts) from IE6.
