Liked the classroom on wheels

Last week's visit to the bus/classroom on wheels was pretty fun. Even though I was only there for part of it, it was impressive. Will this be the new standard, or will it only be available for the schools and districts with the most money? Really liked the cooperative activity and the ability for students to "vote" for the correct answers anonymously. Seems like a great way to get the kids who are shy or unsure of answers involved.
