Do you think they would object to eating off of a plate supported by an electric warming tray? They make small ones that would fit at a place setting.
What about sizzling platters? These are aluminum and cast iron plates that are heated until they can sizzle meat and are placed on wooden holders and brought to the table. They can be heated to beyond the point where food placed on them will smoke. I go to a steakhouse that uses them and I always order my meat rare because 5 minutes after it reaches my table, it sizzles away and becomes medium rare.
Cook with a lot of oil. Oil coats the food and slows down evaporation. Evaporation increases cooling, so if you stop that, it will slow down cooling.
