Old news. Again. I think we all know that all this "CANVAS" thing happens to be is a GUI frontend to a slew of command-line utilities (nmap, aircrack/airsnort, Metaspolit framework, etc.). And it's nothing compared to the ~$25,000 monster from Fluke. I used to have one of those at work and it was GREAT at network troubleshooting, be it wired, wireless (a/b/g/n), or fiber. Real network admins use Fluke devices and a Linux box.
