Give Luis and Maria a demo

By this time you've been through the basic demo almost one hundred times, and you give a very professional, comprehensive showing of the product. Luis and Maria follow along carefully, and interrupt you from time to time to ask perceptive questions.

After you've finished, Luis points out, "You mentioned a picture in picture capability, but you didn't demonstrate it for us. Can you show us now?"

Maria nods.

You smile apologetically and say, "We're still waiting on the final revision of the hardware to enable the second decompression chip. I can assure you that the shipping hardware will support it."

Luis sighs, "Ah, yes. It's just that I have heard many promises in the heat of negotiation that turn into excuses down the road. It would really help us evaluate your offering if you could show us something tangible this weekend."
