Spawn Labs (remember them from TC50?) just started shipping their HD-720 gaming hub. The device allows for two way communication between the player and their console, enabling them to play remotely via a computer, assuming you have a broadband connection.
The device only works with Windows and has some pretty stringent requirements for bandwidth. You must have at minimum 500Kbps for every player, and HD gaming will require at least 2Mbps in order to function. It’ll be interesting to see who comes out ahead in this, Onlive or Spawn Labs. Onlive is currently in beta testing of course, but bandwidth is a problem for them as well.
The HD-720 has an MSRP of $200, and adapters are required for each console connected.
