Hey, I was wondering if anyone could point me in the right direction with this one. I have a fair amount of experience with Cocoa Touch, but I'm new to programming for the Mac. I would like to create a very simple application, where when I press a button in it, it broadcasts a data packet on its local network. I would like to have a similar application that listens for this data packet, and does something when it receives one. Where should I look for help in creating such an application? Thanks!
