I.P. Impulse Software....maybe

[MielkeHBP]

So my laptop will be set up displaying a slideshow for a wedding and I won't be around to watch it so I am taking procedures to ensure that I get my laptop back if it is stolen. I was wondering if there is software that I can install on 2 computers, and I can set up my laptop to send out packets whenever/wherever it connects to the internet display the ip address which its connected to.
