I am not in the peace corps, but I work for a non-profit organisation very simular, and have done that kind of work for the past 10 years. Actually am heading to Belize for a year or more in the morning. I love it and wouldn't want to do anything else.
I've looked into the peace corps several times, but so far have stuck to organisations that are a little more flexible.
I hope everything works out with your application.
