It's kind of surprising that this isn't being done anyway, even if it's not an official part of the show.
How many people would sign up and go to a advanced nats (or into to nats, or both) class at show if TMM put one on? If you are a company that has a product or service this might be a really effective way to market yourself, rather then the same old dinners and parties. Not that I have anything against dinners and parties.
But give an in depth training session in your product. Give a guide to promoting your product etc. That will close some deals.
