May multiple people use a single cup of wine for blessing during a meal?

BlessingsWine During Meal

Synopsis

During a meal, each person must bless separately over wine, even when dining together, due to concern that food in the esophagus could be accidentally inhaled (trachea). However, some authorities permit one blessing for all if people pay careful attention, declare intention beforehand (Svrei Rabotai), and refrain from eating.
