I'll suggest that if your competitive advantage is something so easy to lose that somebody following you around your office for a day could break your business, maybe you should reconsider your business model.
This is even more true for "tech" companies...if you hinge on people not knowing how your special sauce works, you've probably cocked up the business side of things pretty badly.
