There are more live cds around than you can shake an octopus at. And more than I could ever really evaluate effectively. So here are two that I have heard about but have not had a chance to try.
WiFiSlax 3.0 appears to have been released around October of 2007.
WiFiWay 1.0 is another live cd, although I have no idea when this was released.
It appears both distros are looking to fill gaps in hardware support to perform wireless packet injection.
