How can you connect to clients via the internet

I recently jumped on the Go bandwagon. I have tried out this module and quickly noticed that I cannot get it to connect to a different node through the internet. Does anyone have any idea how to do this?

The reason I must know is so I can go about creating a tracker in the worst way possible.
Any help is appreciated.

I would suggest you check out the examples folder, in particular the one named chat-with-rendezvous. That example is really the one that got me started.
