i think the mod could start as first an animation mod, that could be enabled so you crawl/scurry on all fours, itd be cool to have for some the races anyway. and then apply a sticky/grip function to it, having looked at the complex mods available I guess it would just take a programmer willing to do it. the ability to add zip lines, and repel / ropes even ski trails, would be really cool, just imagine dog sleds. maybe we could pool some money together to help out someone to do it. I just personally dont know programming.
