Episcopal Candidate?

We had a guest preacher lead our morning Bible Studies at Annual Conference this year. While she did a good job, I couldn't help but think that she was increasing her visibility toward a run at the the episcopacy in 08.

But how does one get such gigs? Does one approach one's bishop and say, "Bishop, I would like a shot at the episcopacy at the next Jurisdictional Conference, could you contact some of your bishop friends and get them to invite me to lead a bible study at other annual conferences in our jurisdiction?"
