* To analyze the bluetooth protocol for a smartwatch so I could reverse-engineer a phone app to talk to it
* To intercept a temperature logger's TCP comms and figure out how it talked to the vendor's (crap) server software so I could write a better server for it
* To track down a weird problem where ffmpeg won't stream from my home CCTV system (it turns out it sends a duplicate PLAY command, still haven't figured out why yet...)
* To snoop for IP addresses on my local network in order to find lost devices (eg. when someone else set a device to a static IP address which has since been lost).
It's basically a fantastic Swiss Army knife for any question that starts with "what" and ends with "on the network".
