Note that if you don't need wireless, the USB daisy-chain connection is a very convenient way to make several (up to 4 if I'm not mistaken) bricks work together - as you only need to create one program in which you can simply address all ports of all bricks.

It shouldn't be too much different from the NXT's Bluetooth capabilities, from what I perceive.
