More shameless pleas for input

Ok, informal survey. My entrepreneurship group has hit a wall. Our super-brilliant airport terminal fitness center came out with a thumbs-down at the feasibility analysis stage, so we need to proceed with something different. Since we have a good deal of research on the airport concessionaire industry, we want to make use of it and keep the business plan within an airport terminal. But what do airport terminals need that they don't already have? More to the point, what will airport travelers pay for that isn't already available?

Following are some ideas we brainstormed. Which of them do you think you would be most likely to actually spend a buck or two on? If one strikes you as interesting (i.e. you would actually stop and walk into the store), how could we improve it? What would make the sell?

Thanks for any thoughts you have.

• Virtual Golf Arcade--Grab a club, and step onto the astroturf. You can work on that swing before you get to your destination. Or if you're more talk than game, pick up a golf mag and gloves and brag about the last course you played over a beer.

• Urban Nomad Video Gaming Center--Looking for a diversion? Here you can test drive the latest and greatest in gaming innovation, whether it's XBOX, Nintendo, or computer games. Challenge your travel buddies to a Dance Dance Revolution competition, try out the Wii, or ally with complete strangers in a World of Warcraft battle on a 40" flat screen. Oh, and if you can't tear yourself away from the awesomeness, we do sell the games too.

• Urban Nomad Backpacker's Guide Shop--American travel more than any other nationality. And with rising gas prices and compressed schedules, the e-boarding pass is quickly replacing the RV. Just like the US highway system, the airport terrain has its own character and challengers. The Urban Nomad is here to help. Here you can pick up travel books for where you're going, "trail guides" to individual airports (complete with advice on the local wildlife), nifty travel essentials for the backpack-and-jeans road warrior, and even licensed shirts and pins for each airport to advertise how well-traveled you are.

• Airportchat.com--Ever run into people in the airport you already know? Why make those encounters chance? With Airportchat.com you can log in and see who is in the same airport you're in, message them, and arrange to meet up for a drink. You can even meet someone new--hey, you've got an hour anyway! If you're thinking ahead, you can log in when you book the trip and see if anyone you know will be in the airports on your itinerary at the same time. Or if you're looking to meet someone with particular characteristics (say, a venture capitalist), you could even arrange to sit next to such a person on one of your flights (provided that person is also registered on our site).

• Sleep Station--The "coffin hotels" in Tokyo aren't just cool in Japan. Ever see people waiting for flights crashed out on those awful vinyl chairs or the floor (gross!) in the terminal? Ever been one of those people? Wouldn't you rather have a private capsule, complete with pillow, blanket, and luggage compartment? I/O psychologists have been telling us for years that cat naps during the day make us more productive. I'm a fan. Rents by the half-hour.

• 7-11 style mini mart-The idea here is normal, non-airport prices and high volume. Basic toiletries, medicines, bottled drinks, and such at the prices you're used to seeing outside security. Why doesn't this already happen? We have no idea.

• Health food/Juice Bar--Good all-natural foods and smoothies. Not really feeling a greasy burger and soda? Starbucks have too many calories? Vegan diet cutting down on your options? Clear your mind and reach for the protein powder and soy. For dining-in or packaged to-go for a easy unmessy meal on the plane.
