While I'm not interested in taking this, I am very curious as to the metrics and trying to sift through the data to find useful information, like the number of unique SMS addresses sent to, and how many times on average each user sends messages, and to how many students. Is it a teacher sending to 1 class of 30, a lecture of 200, or the entire day's worth of student (multiple classes, but it's the same assignments and due dates). If anyone picks this up I would be willing to try to sift through the data or add the logging code to get the data (email in profile). I don't know what the stats page already has since it's breaking on me. My immediate thought was to try to shift as many messages to email as you can, either through email direct or email->SMS. Then you could split the plans into X emails, Y SMS per month for $Z. That way you could tier the plans, potentially creating something for schools to buy to let all their teachers use.
