I just find it extremely unethical to request such a thing from brokers working at another shop. I know my employee agreement, and I'm sure just about every other agreement, has a non-compete clause along with an IP protection clause, and asking someone to send you files from their shop is tantamount to a lawsuit. Both to the employee and to you for soliciting them in this fashion. I know you would hear from my lawyer if I found out one of my guys was trying to backdoor my clients to you for some extra cash.
