I would think it would be cool if the 3darcade would end up in other frontends...it would mean more support for models, backglasses and playfields and videos etc. And maybe mame on the cabinets themself
Not to mention that, but the presevation of a vital part of arcade games, mainly the cabinet itself! It's easy enough to store a rom image on your hd, or an old pcb in your closet, but cabs are often destroyed because they're just to darn big to keep around. I know we are no-where near this far along yet, but we could have cab owners submit measurements and photos of their cabs, so even if the actual cab perishes, there's a farily accurate 3d model of it available for anyone who would choose to re-create it in the future.
Oh I had one of those crazy ideas of mine last night. You could have the flyers and other misc artwork display in yoru 3d cab as well. Just when you stop scrolling, a large translucent panel could display the flyer in it either to the left or the right of the cabinet selected. Or you could even stretch the image around that cylinder in the bg. Just a thought, I know I'm jumping the gun now.
