I cant go but Ive entered a photovore (solar powered phototrope) as a run by proxy (I mail it to them and they put it in the arena and run it). Id like to enter the ribbon climb but there may be a bit too much setup to do it by proxy. So if anyone is going and would like to take part in a non combat challenge, please get in touch with me. Ill build the ribbon climber and mail it to SF so all you would need to do is operate it.
