Well, i'm the main developer of WEllenreiter, please take a look at 0.9 version. Its in some things more advance than kismet but does not support gps, but soon it will work. I actualy try to support nearly all cards..1.0 will support cisco, prism2 and maybe if i can organize one also lucent ones. But basicaly i dont fear to be compared with any other software on in this range. Personaly i think its better then
kismet acouse of the gui mostly, the featureset is nearly identical. And Wellenreiter can easely export the savefiles to cvs for example. And the dumpfile abilitiy gives you the chance to use ethereal to examine the whole session recorded in more detail.

Greetings

Max
