you are right of course goofy one, but i think this deserves another look since dock handling has been improved since then. In fact I was the first one to vote in this poll.
i think one option has been left out now with all the multi dock apps available. It is possible to have one in a varity of these positions now. i tried that for a few hours and found it to be too confusing but i can see how some could make it work with no problem.
