If you want to get user input from clients (which makes it a lot more fun), then try to use a sms gateway.
Clients come for socialize and fun, it's to much hassle to hook up with wifi and such,
most people even dont know that they've got wifi (not everyone uses a iPhone), but they al do texting(sms).

When the client sends a text it'll show up on the big screen. "Jimmy caused the Jack Daniels stocks crash!!!!"
Consider the marketing value of having all your clients cell numbers.
About the stocks values:
High demand rises prices, low demand lowers them.
Hire a good looking babe to order a drink that nobody drinks ( the one you've got plenty in stock)
