So ... CodeWorkout relies on a separate server for the OpenPOP visualization engine, and there is currently no goal of trying to merge this into the CodeWorkout codebase. Instead, a separate group manages that server and the work necessary to operate it. Currently, that design has significant limitations. If you are already working with Cliff Shaffer's group to pursue this integration, please contact me to set up a meeting so we can discuss the issues at play before we can consider any pull request of this nature. Thanks.
