Replying to JOSS: what about rails/boxes?

I know Jon doesn't like rails or boxes as much as jumps but I read something about him wanting JOSS to incorporate all parts of the filming, photographing and skiing. With his amazing jump building I think there should at least be one or two good rail features so the riders don't have to go to the park for not so legit features. I was thinking a big disaster flat down box or a cannon box or just a really advanced and manicured rail park who knows maybe something we've never seen before. I know they could still get some urban shots but what the hell is Candide gonna cork 810 onto?
