Go here now! This is so totally the ring on my phone now.
Also, just to remind myself in the future. There is a certain program made by a certain company that allows you to run certain other programs on a certain operating system that you ordinally wouldn't be able to run on said operating system. This same certain program does a certain annoying thing involving port scanning a network to see if this certain program is running on certain other machines. I don't like port scanning. If you don't like port scanning either, then open up Terminal and run this certain command:
sudo ipfw add deny udp from any to any 21790 in
