Place 1/2 cup of the milk in a medium bowl and sprinkle with gelatin; let stand 5 minutes. Bring remaining 1 1/2 cups milk to a boil in a small saucepan over high heat. Add to gelatin mixture, whisking to dissolve gelatin.
Process gelatin mixture, yogurt, 5 cups of the strawberries, 3 tablespoons of the honey and 2 tablespoons of the lime juice in a blender until smooth.
Slowly pour mixture into 10 (4-ounce) ramekins or molds. Refrigerate for 8 to 12 hours.
Stir together remaining 2 cups strawberries, 1 tablespoon honey and 1 tablespoon lime juice. Let stand 10 minutes. Spoon about 1 tablespoon of the berry mixture over each panna cotta; reserve remaining for another use.
