I doubt they replaced much of anything. One of their screenshots shows a link to gazpacho for crying out loud. Their interface is basically 3 buttons. I wouldn't be surprised if they have cobbled a Python frontend together on top of open source console tools. Hell, their one 'scanner' screenshot is the standard 770 wireless network locator dialog. What amateur hour crap. This really annoys me. And the press cries out in their ignorance that this is a first of its kind pocket scanner.
