I'd be more interested in trading produce for food. I produce a pretty fair amount of milk and meat, and could produce fruit and vegetables if I had reason to do so. If I could get back some reasonable portion of the food produced, that'd be interesting to me.
so you go to people's houses and cook the produce they have in storage? It would be kind of cool if you could do that during a party, continually refreshing the cooked food supply and offering people drinks. You'd have to have a lot of big bags and maybe an assistant or two so that supplies would not have to be put on the ground where they could be stolen. Food thieves at parties ruin the mood.
