I know this is an ancient post (2006) but..
I answered the poll with a "for always". Honestly, it's our second job but someday we see ourselves doing more with it. Hopefully it be the only job. I'd like to somehow get involved with networking with tutors of other languages besides English and perhaps do a co-op learning center. Since I live in an area with many cultures, I'd love to arrange classes for people looking to explore other languages. French, Arabic, Portuguese etc. Now logically figuring all this out is another story.
Thank goodness I'm used to being self-employed and having weeks of basic vegi lentil stew or weeks of good bottles of wine and cheese.
