Maybe they could be a new child board to the student's corner?
The 'project' model, based on the ones I've seen in student's corner, is for those who need assistance with technique, technical difficulties, execution of notes or practice techniques. If you're a pianist who have the stuff on the 'project' model nipped in the bud, then you're best off using the audition room. You'd record yourself, critique your own playing and cover what went wrong with it to the best of your ability. If you get really stuck somewhere and you need someone else to hear your performance, then that's where the audition room is used. Where does interpretation fit in? Since you can try out different interpretations for the same piece...
Since my name was mentioned by Marg, I feel that I must add my two cents to this thread. II think it's a good idea to begin a thread asking what pieces would be of interest to many members. They could post their ideas on that thread and if there is enough interest in a piece (at least 3 members and even better, if some teachers would volunteer), these three can get together to begin a project rather than each individual starting a project. All members of this project team MUST agree to contribute with videos often and regularly, thus making the project interesting and motivating for everyone.
