San Francisco Giants' SBC Park plans to allow visitors to watch instant replays via Wi-Fi: The park is already covered by Wi-Fi and next season guests will be able to use their PDAs or laptops to order up instant replays. Apparently many parks around the country are planning to offer Wi-Fi access.
I'm starting to notice that an increasing number of Wi-Fi services are beginning to make unique offerings. The first stage of Wi-Fi was all about getting the networks up and enabling basic Internet access. Now that it's clear that's doable, network administrators are thinking up creative ways the connection can be used. I expect to see more and more applications like the instant replay popping up on networks anywhere.
