David,
Survey is the survey package that was commissioned by Sloan for dotLRN. It should replace simple-survey. Its too bad aD chose to name packages wimpypoint-slim, simple-survey etc.. instead of just using a logical name that would make sense for the future, and make it easier to upgrade.
Survey is inspired partly by the work done my Malte for ACES, but we had to do most things a little differently to meet the requirements for Sloanspace. There aren't any scripts to upgrade from a simple-survey installation to survey, but I think we could create a way to bring surveys over from simple-survey to the new survey package.
