Question: I would like to use [I/O Ninja](http://tibbo.com/ninja) as a portable application, from a USB stick, without installing it. Is that possible?
Answer: It's sort-of possible, but not entirely: Both the sniffer and serial monitor require services (WinPCap and Tibbo Device monitor, respectively). However, socket and serial communications require no services, and _can_ be used without installing Ninja.
So, if all you need is just socket and serial comms, you can simply copy the Ninja folder onto a USB stick and it should work. Good luck!
