How smart is smart enough?

So today one of my many listservs contained an e-mail that announced a job. Immersion (an institute for Information Literacy that is world wide, and is highly selective of its participants) is seeking 1 new faculty member. This is in addition to a permenant posisition. So I could keep my regular job and this would be in addition to it, take 1-2 weeks full time work a year, and a lot of reading a preparing the rest of the year. Am I crazy for even wanting to apply? Not crazy because of the time committment, afterall I am finishing up my second Master's degree while working full time (this will be completed in May, hoorah!). But, this faculty at least in my mind, is elite. I have only been a librarian for 4 years, am I really qualified to apply?
I attended Immersion as 1 of 90 selected participates in August 2005 and it was awesome, I learned so much. If I could help other librarians get passonate about teaching, which is something we all should be doing, it would be so fullfilling. One of my long term goals is to earn my doctorate degree and teach in a library science program and this would go a long way in preparing me for that. I'll keep you posted.
