Kartique makes a transporting kart stand that slides onto a receiver hitch. The wheels fold up and you put the kart on top, when you get to the track or home you pull it off the hitch fold the wheels down and you have your kart stand! Small trailers are great but you still need a kart stand ounce you get there, this does both. They are available at Action Karting (Bandimere) or CRE for $379.95 and come with the hitch adapter.
I was actually considering building something like this so I am very intrigued! I will have to go check this out.
EDIT: Looks like this is what you are talking about?:
