I'm not involved with this startup, but I did hear a bit about it from someone who was at the StartupWeekend in Seattle where it was realized. From what I remember, they did have a teacher on the team - and were recognized as one of the stronger groups for this reason. Also, I don't see any information about it on the site, but I think that one feature of the site may be that the teacher's bosses (department heads? headteachers?) can review all the communications. Hopefully that mitigates the legal risks a little - even if only because teachers would be more careful about what they text.
