Actually, the rule says that "water based fire fighting equipment shall be present on the field." I doubt that a coffee cup of water would be seen by anyone as "water based fire fighting equipment." As far as the gripe that the rules are not specific on what constitutes "water based fire fighting equipment" I'm glad they left it to our discretion as to what is reasonable fire fighting equipment instead of laying out exactly what we need. That way, we're left to our own intelligence to figure out what is best to counteract the risk that is involved - a rare thing in our overly risk adverse society. Would it be better if it said that "water based fire fighting equipment consisting of an International 530E engine capable of carrying 1000 gallons of water and pumping a minimum of 50 GPM shall be based at the field..." Just buy the Indian Fire Pump, keep it filled and bring it with you to the field, its as simple as that. A small price to pay to keep from burning down somebody's property, or worse yet, having someone get hurt by a turbine-started fire, and heck, bringing it out reinforces the idea that these are serious model airplanes that are a blast to fly, but need to be operated with a bit of care - not a bad thing in my mind.
