<font color='#000000'>Brett,
I could see this as being a logistics issue. For example, if IR actually did this, I can see forum threads lighting up with people posting serial numbers, or even selling serial numbers for that matter.
Besides, that would leave the owner with two units and will cost IR significant money for selling the $4,500 unit for $2,000 less. It's a good thought, but I don't see how it will work. Too many issues with serial numbers only.</font>
