Hi there, i read your post and well i dont quite understand where your coming from. If you use back track in parallels you really aren't using the mac os (lion), your using the operating system of its environment, ie, you set up windows in parallels, and anything you use in that is windows driven, same goes for the linux core on your parallels, so in theory anything you use in that section is linux driven. Be aware that anything you use in parallels linux cannot use host or sub host drivers, the net connection will work as its shared with the host system, in your case mac osx or lion whatever you want to call it (10.7) you can use any of the "tested working" USB wifi adapters, providing they are USB as your parallels system will have access to you usb ports, but make sure they are supported by backtrack as backtrack uses its own drivers unless you want to edit code ! There is a post on the web from "dishingtech" who describes in detail how to install backtrack using parallels and how to get it all working, he also provides all the code if you want to mess with it yourself, and a downloadable image of the setup files, you might want to check it out. I use a macbook air and usb Alfa, in parallels both in injection and passive, it does work well, and yes i use 10.7........hope this helps
