I really like the concept but I wonder if doing it with someone external to the company is a good idea for those of us with NDAs, confidentiality clauses and so on. Especially if it is done using a communication channel that hasn't been approved by the company. I suppose you can keep the details vague enough if necessary, but if I was a spy, this is definitely something I would try to do with my target.
