iBlast? It looks to be a great thing but as of yet only works on a wintel, it shows much promise and could be the next internet service system.
Not iBlast, however there are other companies that offer the same type of service. There are security concerns surrounding wireless service in which people will go around with their laptops and look for holes or open ports. People will not properly set their security preference on their wireless system, inviting invaders.
Online gaming should be free to the public anyways though.
