Pi Finder

I'm putzing around with my Raspberry Pi again, and came across Ivan X's Raspberry Pi Party site. One of the utilities he has which you may find useful is Pi Finder, a program to find and connect via SSH to your Raspberry Pi running in headless mode, when you don't know its IP address. Pi Finder is an app that runs on Mac OS 10.5+.

If you need a similar app that can run on Windows or Linux (plus Mac OS X), check out Adafruit's Raspberry Pi Finder.
