Not likely for a large multinational to develop their own software. My experience tell me that they will purchase rights & the adjust it to meet their specific needs.
The real opportunity for phone guard is with fleet vehicles. Valid points about kids & parents not spending money to reduce texting.......companies do not have this luxury. No texting while driving is already policy & app's like phone guard is the next step. If not, legal ramifications will be huge when accidents occur during the business hours.
